Not sure why the command knob in Mazda scares new users: it’s an option and you still could use the touch screen, it’s just a nice alternative for it…
Absolutely love the command knob, so much better than using the touch screen
I realize the article is pro buttons. I think a huge thing missing from the button discussion (well, maybe lightly touched on in the article) is that physical buttons and controls help guide without looking. Other buttons give feedback that your hand is in the right place. Sure, at first contact that (very bad) reference radio is worse than the touch screen but within a few days of using that I would not need to look to make sure I was hitting the button I wanted because I could feel the face of it with my hand and know I was hitting the right button. So basically, even though the paper picked essentially the worst radio on the planet, it would likely be better than a well designed touch screen after just a few days of use. First day though? That thing is a nightmare.
A while ago I was driving a loaner car - a brand new top tier Accura rdx and the infotainment system was truly the worst and most dangerously designed I had ever witnessed. It was essentially a lenovo thinkpad type touchpad by the cup holder, and the screen was far away. The first time I tried to use it, it was so distracting that I would of crashed the car if it weren't for the safety features.
My car is a 2018 with car play and physical scroll knobs and buttons, while awkward, I can operate it with my eyes on the road (realistically I can do everything I need from the steering wheel). This weird middle ground carplay was somehow the worst combo of buttons and touchscreen.
Totally agree; I had to cut a few sentences about that :). (I also tried to steel-man the paper as much as possible).
Oddly enough, it seems like, although the value of "blind operation" is well-understood, it's not super well researched. As one of the papers I cite puts it:
> Little research deals with the optimal design of haptic features and how haptic feedback can support the user in searching for control elements.
They're getting better though. The first gen touchscreens were tiny and unreliable. The one in my 2024 Ioniq 5 is pretty decent. I am really glad I still have physical AC controls though, even if they're capacitive.
Touchscreens are modal. If I want to control the climate, I first have to press the Climate capacitive button or scroll through the screen to find climate. That takes my hands off the wheel and my eyes off the road for longer than just tapping the fan-up button.
As for the cost, I will _happily_ pay the $100 more to have a more premium and tuned interior. Heck, I chose to step up an entire trim model to the top of the line trim just for the fancy LCD screen mirror. I'd happily pay extra for better buttons.
IMO touch screens are great for rarely used features, but anything that gets clicked on most drives should be a dedicated touch point (capacitive button, physical button, steering wheel control, whatever).
Give me multifunction displays from aviation. Touch screen in the middle, rows of modal buttons along the bottom and left side. You can use muscle memory to find the button.
Touch screens don't have to be modal, that's a UI choice. The 2020 Bolt we just got leaves the climate controls on screen at all times, even when CarPlay is open. I was also pleasantly surprised by the number of buttons it has, including both a volume knob and a temperature knob.
That being said, the touchscreen software is abysmal and laggy. CarPlay works great, but any time I have to navigate the car's built-in software is a headache.
> I will _happily_ pay the $100 more to have a more premium and tuned interior
I'm guessing the cost difference is greater than this. Which means the end-user price difference would be north of $1k.
Would be interesting to see if customers would pay $2 to 5k extra for a mostly-tactile interior. (I think back-up camera requirements make some screen unavoidable.)
I'm somewhat skeptical that the cost difference would really be that high, but honestly...yeah I probably would. If what I was getting was fully physical (not capacitive) media and AC controls, including pause/play, skip/tune, volume control, temp control, fan speed control, zone selection, etc? I interact with those systems multiple times every single time I get into a vehicle, which is essentially multiple times every day, for years. Improving the quality of those interactions even a little bit (and in my opinion the difference between good physical buttons and even a very good touchscreen, let alone a shitty one, is massive), is worth thousands of dollars.
While I was not presented with the option on a given model to go with buttons or touchscreens, when I was shopping for cars, I did eliminate models based on their interface options. The models I was willing to consider were probably cut in half because I wouldn't get anything that was entirely touch screen or capacitive for both AC and media.
Do you not have muscle memory for screens too? I find my brain has an easier time visualizing all the touchscreen controls I use semi-often over buttons. Perhaps it's a generational thing.
I have heard (but have no insider knowledge) that it's not just the cost of parts, but what parts do to the development lifecycle.
With physical parts, the development process is highly sequential. Pick the look, design how it fits, engineer what parts are used, manufacture tooling etc etc in a waterfall. If a revision needs to be made, the whole process needs to be re-started adding a huge amount of delays.
With a touchscreen, the physical touchscreen and the software that runs on it are parallel threads. You can make most UI changes without impacting the manufacturing/design pipeline at all. You don't even need to have planned what the interface looks like before you finalize the parts needed.
More importantly, car touchscreens are dangerous. It’s impossible to operate a touchscreen without moving your attention from the road to the touchscreen itself.
That’s why I think it must be a legal requirement for any car with touchscreen controls to operate car functions must have driver assistance features enabled, no exceptions.
Mazda’s rotary knob also has safety issues. Let’s say I want to zoom the Google Maps in or out in CarPlay) at some point in my navigation.
With the knob, you have a few issues:
1. iOS made the focus border on UI elements very faint. So it’s hard to tell where the knob is at rotating through all the UI elements.
2. Because zoom is kind of a sub feature, you have to rotate through like 10 buttons to get to the right thing, click, then get into a submenu.
3. Because not many apps design around the knob… the active “cursor” can get trapped in a submenu where the knob just rotates between a few buttons and can’t escape back to the root of the app.
Basically, it takes active attention to zoom in/out. Touch screen, I could probably do it without looking.
Just like the article mentioned, you can't just say that touchscreens are dangerous without bringing up how many buttons do not make it better UX. There are plenty of touchscreen designs that are way better than buttons.
The only metric that matters is how fast you can get attention back on the road.
Simple. I can operate any button without taking my attention from the road at all as long as the said button has a distinct feeling and/or location. That’s immediately an infinitely better experience.
BMW iDrive buttons are an excellent example for that.
> It’s impossible to operate a touchscreen without moving your attention from the road to the touchscreen itself.
The article directly links to a study that shows this is also true of physical buttons. Regardless of the fact that buttons are tactile, people don't go feeling up their radio without looking, even if they can. Furthermore, the vast majority of infotainment input today is into phone mirroring systems like carplay.
This whole thing is compounded by the fact that Mazda's knob solution was actually worse while being marketed as better. While a touchscreen needs to be looked at to find a button, a cursor controlled by a knob needs to be watched in whole to navigate to the button. Your fine motor skills as a human allows you to directly press a button, physical or not, without looking at your arm to get near it.
You're right in that with a physical control you still probably glance at it as you're reaching for it, but you don't have to keep your eyes on it the whole time unlike a touch screen. With a touch-screen there's no feedback that your finger is on the button and that you have actually pressed it. With a physical control, button, knob, or slider once you have your hand on it you can manipulate it without looking. They demand momentary glances, not seconds of constant focus.
Well, it depends on button and function. Rarely used functions will require looking, common ones (assuming button placement is sensible) will not, but even ones that require looking are still better because you skip going thru the menu to find it.
> car touchscreens are dangerous. It’s impossible to operate a touchscreen without moving your attention from the road to the touchscreen itself
They're dangerous for controls the driver would reasonably need to operate while driving the car. They're fine for more-complex at-rest configuration, or stuff a passener would care about.
OP here: I always disliked touchscreens in cars, so I didn't understand why automakers kept shoving them in. I always assumed I was weird in some way, and that most consumers preferred touchscreens or something (Reddit seems to argue this in circles all the time). I planned to keep buying Mazdas, with their lovely buttons and stuff.
But when Mazda unveiled their button-lite 2026 CX-5 about a year ago, I started investigating.
I'm pretty convinced that touchscreens today are primarily a cost-saving measure, and every other justification is secondary. I hope I can convince you, too!
> I'm pretty convinced that touchscreens today are primarily a cost-saving measure, and every other justification is secondary. I hope I can convince you, too!
It amuses me that back in the 90's LCD color screens were magical fairy dust that cost about the same as what magical fairy dust would cost. Laptops with color LCD screens were like $6000 in the 90's, I think $3k over a greyscale. That's like $13k today.
Whereas the little plastic buttons and knobs were cheaper to pump out of an injection molding machine and assembled. Now screens are cheaper to make than little plastic baubles.
> I'm pretty convinced that touchscreens today are primarily a cost-saving measure, and every other justification is secondary. I hope I can convince you, too!
I thought this is a pretty well-known thing already? For almost decade.
OP: Perhaps it is, but this article honestly took me 12 months to research & write. I really struggled to find trustworthy sources. Do you know of any others I should look at?
> so I didn't understand why automakers kept shoving them in.
The article explained why. Since 2018 in the US, due to the proliferation of giant trucks being used as passenger vehicles (SUV's) backup cameras have been mandatory safety equipment. A backup camera requires a screen. So the automakers have to install a screen in the dashboard.
It is only a few dollars more to install a "touch screen" vs. a "basic display screen", and with the addition of those few dollars to the screen, that touch screen can now replace hundreds of dollars of physical buttons and their necessary wiring.
Net result, the BOM cost of the car drops by several hundred dollars, and the cost to assemble drops by some measurable amount as well.
So they why is: "because they save the automakers BOM and assembly costs".
Obviously they read it, but it's 2026 and entirely possible to publish an article without having read a word of it :)
All that said, I think initially it was a mix of a few things coming together.
Yes, auto mfgs always want to reduce parts for cost and supply chain control. But there was also this moment of New Wow where the impractical nature of touchscreens was overshadowed by the holy crap I've got a tablet in my car. It implied a break with the last generation of cars, where you might have gotten a 4-inch screen (touch or not), and it became desirable at a surface level to users.
Although I greatly dislike touchscreens for the obvious usability issues in a motor vehicle, I still kind of widen my eyes when I'm in a car with some new, ridiculous multi-screen dashboard setup.
Mazda was mentioned in this thread, and I think they do a great job of separating the concerns here; you've got a big buttons of various sizes that do different things that can be memorized without sight.
I love the click-wheel on my Mazda3 and I love that it allows the screen to sit out of arms length up on the dashboard. Its a very nice interior. What I don't love is how Android Auto is slowly breaking since it assumes more and more that you have a touchscreen.
It used to be that it would focus buttons in notifications, making it easy to interact with. Now the focus doesn't seem to change at all (or only sometimes) making it a nightmare to do simple things. I dare not use the new Gemini assistant since the last time I was completely unable to navigate to the buttons in its panel at all.
I really hope they don't phase out the wheel just because Google sucks at supporting it. I know they have both touch and the wheel in newer models now.
I cried when Mercedes go rid of the click wheel. Research in this article be damned, I’d argue that rotary knobs with directional shifting like Mercedes paired with great software are the best car infotainment interface in recent history for screens in cars.
(a) cars have forward-facing cameras/computer vision for lane tracking
(b) infotainment systems have always-on cellular internet connections
(c) billboard impression counts can be tied to the vehicle
IIRC infotainment systems are already showing ads in some form. And location + driving performance is being captured + monetized and shared with insurance companies.
Unless this results in an EV car that I can rent for less than $100/mo, this really needs to be stopped.
I think they've got that. Short of budget stuff or the Slate truck, most new cars have some big dumb screen in them at all times.
But advertising poses a new problem for both advertisers and mfgs not unlike the mid-90s ad sale issue. There was no consolidated ad server, so everyone was trying to build their own agency and advertisers had to navigate that.
Which probably means some sort of Google or Google-like player in the space.
I think that nowadays people value "technological features", and how better to show "technological advancement" like a giant ass touchscreen and not some "old" XX century knobs.
I hope that changes and people start valuing simplicity and robustness over electric gimmicks (I know many people already do, but we need critical mass).
How much is that needed? There was very little text on those buttons to begin with. Are there significant cultural differences in the iconography associated with them?
Sure, touchscreens are cheap, but high-quality touchscreen software is most def NOT CHEAP!
Apple and Google have spent untold amounts of money developing iOS and Android. CarPlay and Android Auto are really nice.
Tesla has spent gobs of money on its touchscreen software too. It's the only native car touchscreen UI I've tried that feels smooth, snappy, responsive, simple.
I've tried the native touchscreen UI of quite a few US and European carmakers. All of them fall short. They feel janky, clunky, obtuse.
Physical buttons are much, MUCH cheaper than high-quality touchscreen software.
There has been more pushback on car screens over the past couple of years, and the optimist in me hopes this leads to change. With enough pushback, manufacturers will have to listen to the market, cost savings be damned.
A concrete step I take to push this along: I mention physical buttons as a dealbreaker to car dealerships when I shop. Of course, I'm only speaking to dealer reps and not the decision makers at $CAR_CO, but if enough people do this, it does get back to the them and will make a difference.
I could not imagine having to go back to buttons for anything I actually want to control. Once you get used to a well-designed touchscreen, buttons are just so clunky and unintuitive for most functions. Dials are probably my most favorite physical control, but other than volume there's not much it's useful for in a well-designed, modern car anymore. It was great for radio stations, but is terrible for Spotify.
Setting temperature manually by dial doesn't make sense anymore either- most cars have too many things to change and an expanding menu is great. There's hot cold, faster fan lower fan, feet vs head-height (we're already looking at more than three separate controls). Now there's seat heating and cooling (with varying power), steering wheel, defrost, controls of vent direction, etc.
I'll admit the touchscreen might be daunting if it's a rental but it takes like one week to get everything mapped out mentally (and going back to physical controls on rentals sucks).
That works as long as you actually stick to your guns and keep them as deal-breakers. If you accept them with some grumbling, that's still a sale and that provides no backpressure to the manufacturer.
It has already started asking for physical buttons for key functions to give manufacturers the top safety rating, and it's working. Buttons are coming back.
Their source is "a Swedish motoring magazine in 2022". Europe sure does love regulation- no desire or call for finding the best way to implement vehicular controls, just a desire to lock in old functionality with a flimsy excuse.
My biggest issue with touchscreen controls is that they are not ergonomic.
1. Usually they are high on the dash, higher than where conventional controls would be
2. You cannot rest your hand on the surrounding panel to press them, because this will cause unintentional presses on other buttons
Resulting in two problems:
1. Because of the above, you must activate more muscles to steady your hand and arm in a moving car to accurately press them. This is less comfortable and leads to frustrating misclicks
2. This increases the amount of time required to use the controls, which is annoying for infotainment, but dangerous for anything safety related
Neither of those are a problem in my 2015 Tesla Model S for the buttons that control the climate control or media player.
It seems to me that many of the problems that people report related to touch controls are more to do with how they are laid out than the fact that they are touch controls.
The $6,000 profit per car referenced in the article is gross profit, not net profit. Net profit is considerably lower, around 5% for the mass manufacturers. So a $100 cost savings is very significant against a ~$3,000 net profit on a Bolt.
I want to cheer (again) for my 2020 Ford Escape. Its infotainment design was a significant differentiator that led to my selection after testing a dozen different models across all US manufacturers.
It has Carplay/Android Auto, naturally, but it also has physical buttons for play/pause/previous/next and volume, and physical buttons for A/C control. All buttons have a single (sometimes dual) fixed purpose, they don't change purpose depending on whatever mode something is.
It is, in my mind, an ideal amount of buttons compared to, say, the Honda CRV or Toyota RAV4 at the time that had extra buttons around the screen for flexible features, meaning those buttons had no fixed purpose.
I hear the Escape was actually designed for the European market (as the Kuga), which may explain its design sensibility.
Unfortunately, the Escape has not been a roaring success, and Ford will discontinue it in the US market in favor of the Bronco Sport which has, you guessed it, a huge touchscreen and few physical buttons.
I gotta say, the one redeeming feature of Ferrari Luce, for me at least, was the interior. I don't dislike screens, I just hate the tesla-esque obsession (where, for them with FSD - for all the hate they get about it up here - it might actually make sense since u are gonna have a FSD+Grok car) with no buttons. I know buttons add cost, but going back to the Luce example again: you have a healthy sized screen (so u don't go to the pre-tesla days), but you also have wonderful buttons across the board.
Now, I know it's not a very representative car. But nobody said the buttons need to be as flashy or as numerous.
Tesla arguably has better, more useful, and more obvious physical buttons than most cars. Most car manufacturers spray confusing physical buttons everywhere with esoteric icons and insane UX. Everything you'd want to do as a driver in a Tesla has a physical button or a set it and forget it "auto" mode.
Uhm, I like Teslas a lot. The design and the philosophy of just minimizing the amount of components. But where I would draw the line is AC via touch screen (again, if Grok can now do it reliably, fine, otherwise, buttons please). Also, depending on the model, I know some models had turn signals in some weird places (above the head? or am I hallucinating?). Also to make your point: if it hadnt been for carplay and its android equivalent, legacy auto would have been cooked long ago. I never use my VW native apps.
My point being, I think we havent found the sweet spot yet.
For touchscreens, I think there is an opportunity to make larger touch targets. For example, when you want to adjust HVAC controls, the UI should take over the ENTIRE screen with ridiculously huge targets. Something in the range of 1-4 square inches in size for a core button should allow your for reduced cognitive overhead. This is critical for safe driving.
I think its easier to develop muscle memory to certain buttons. For instance I had a similar 1DIN head unit to the one pictured in the article. I never needed to look at it to operate it.
There was a study from a few years ago that associated almost all increase in traffic deaths in the past decade or so with in car displays. Almost all deaths were pedestrians being struck at or after twilight. The thinking is that infotainment systems are making drivers take their eyes off the road to adjust anything in their vehicles, and also ruining their nightvision. Not sure how they were able to separate this from smartphones.
As an engineer in R&D, I've always known if I needed a cheap but amazing part, to look at automotive replacements from third parties for parts to build an MVP with.
Those rear hatch motors are amazing and most have indexing.
I think there is a real market for modding news cars to have physical buttons again. Whenever this discussion pops up on the internet, there's plenty if people who prefer them (they're called "old folks" ;-)) so why not mod your dashboard to feature a - wait for it - volume button for your music!
I wonder how much can be controlled over some kind of bus. Would be cool to have all sorts of physical buttons and a micro controller to control radio, AC, heated seats etc etc so I can keep looking at the road while changing things.
The volume button (dial) broke on my Ford Maverick in summer. Moving to a touchscreen car felt like a sigh of relief that I no longer had to worry about buttons and dials breaking when I need to use them, and don't have to worry about a trip to a dealer or tearing apart a dash to replace them.
I will say a button "feels" nicer, but the added risk to me wasn't worth it. To each their own
> wait until the whole thing is unresponsive due to heat or a bug
Chances are if the whole thing is unresponsive due to heat or a bug the volume knob isn't going to actually change the volume as well. Its not like the knob is the actual pot directly changing the circuitry in the amp these days, its a digital input.
I've personally experienced it on at least six different car infotainment systems by four different manufacturers where the stereo will start playing whatever was left on, you turn the volume knob but the whole thing is still loading so it doesn't react for a few seconds.
Even outside of OEM head units, I've owned a few after market head unit stereos where the volume knob was technically a digital input and if the system was lagging hard the volume input could be delayed a good bit.
A number of these systems will have a different volume level for things like phone calls than for the music, but both volume levels are controlled by the knob. It'll also do things like automatically lower the volume level for notifications or have dynamic volume levels based on acceleration. The knob is rarely directly controlling the actual output of the system.
Here's a good question: if you press the volume buttons on the steering wheel controls, does the volume knob on the radio move?
car touchescreens are in the same category of most laptop webcams/cams: just make it good enough, and make it fit (and they both suck, most of the time)
Maybe people should stop buying cars with crappy touch screens then? The touchscreens in my Model 3 has been amazing. Ever since I took delivery of it in 2019. Manufactures need to do better.
Lordy I hope not. Cannot imagine having to childproof my car's entertainment system, or make sure I don't sing a trigger word, or try to turn on the defroster to dehumidify the windshield during an intense rain storm where I can barely hear myself think.
Also: I don't want a microphone in my car at all times. Thank you.
It could use array microphone to detect that the sound originates from the driver's seat (in addition to using it for filtering out not-from-driver's-seat sounds).
I mean that's cool, if it actually works reliably. Automation tech enthusiasts are willing to be impressed by 99% reliability. To get buy-in from regular people, it needs to just work better. To be clear, I don't know how reliable this actually is now, but I'd be willing to bet that it's not reliable enough.
No. No, please, no. I won't buy a car that relies on voice for anything, and I really don't want to rent one either. Wildly inefficient, slow, unpredictable.

> car touchscreens are dangerous. It’s impossible to operate a touchscreen without moving your attention from the road to the touchscreen itself
They're dangerous for controls the driver would reasonably need to operate while driving the car. They're fine for more-complex at-rest configuration, or stuff a passener would care about.
OP here: I always disliked touchscreens in cars, so I didn't understand why automakers kept shoving them in. I always assumed I was weird in some way, and that most consumers preferred touchscreens or something (Reddit seems to argue this in circles all the time). I planned to keep buying Mazdas, with their lovely buttons and stuff.
But when Mazda unveiled their button-lite 2026 CX-5 about a year ago, I started investigating.
I'm pretty convinced that touchscreens today are primarily a cost-saving measure, and every other justification is secondary. I hope I can convince you, too!
> I'm pretty convinced that touchscreens today are primarily a cost-saving measure, and every other justification is secondary. I hope I can convince you, too!
It amuses me that back in the 90's LCD color screens were magical fairy dust that cost about the same as what magical fairy dust would cost. Laptops with color LCD screens were like $6000 in the 90's, I think $3k over a greyscale. That's like $13k today.
Whereas the little plastic buttons and knobs were cheaper to pump out of an injection molding machine and assembled. Now screens are cheaper to make than little plastic baubles.

I thought this is a pretty well-known thing already? For almost decade.
OP: Perhaps it is, but this article honestly took me 12 months to research & write. I really struggled to find trustworthy sources. Do you know of any others I should look at?
Also, I rather like the idea that blogging can simply be stating the obvious: https://blog.jim-nielsen.com/2026/blogging-stating-the-obvio.... Hopefully my argument is helpful to someone!
I figured it was the most reasonable conclusion via Occam's Razor. Economical and the illusion of futurism
> so I didn't understand why automakers kept shoving them in.
The article explained why. Since 2018 in the US, due to the proliferation of giant trucks being used as passenger vehicles (SUV's) backup cameras have been mandatory safety equipment. A backup camera requires a screen. So the automakers have to install a screen in the dashboard.
It is only a few dollars more to install a "touch screen" vs. a "basic display screen", and with the addition of those few dollars to the screen, that touch screen can now replace hundreds of dollars of physical buttons and their necessary wiring.
Net result, the BOM cost of the car drops by several hundred dollars, and the cost to assemble drops by some measurable amount as well.
So they why is: "because they save the automakers BOM and assembly costs".
They're aware. You're replying to the OP of the article, lol.
Obviously they read it, but it's 2026 and entirely possible to publish an article without having read a word of it :)
All that said, I think initially it was a mix of a few things coming together.
Yes, auto mfgs always want to reduce parts for cost and supply chain control. But there was also this moment of New Wow where the impractical nature of touchscreens was overshadowed by the holy crap I've got a tablet in my car. It implied a break with the last generation of cars, where you might have gotten a 4-inch screen (touch or not), and it became desirable at a surface level to users.
Although I greatly dislike touchscreens for the obvious usability issues in a motor vehicle, I still kind of widen my eyes when I'm in a car with some new, ridiculous multi-screen dashboard setup.
Mazda was mentioned in this thread, and I think they do a great job of separating the concerns here; you've got a big buttons of various sizes that do different things that can be memorized without sight.
I love the click-wheel on my Mazda3 and I love that it allows the screen to sit out of arms length up on the dashboard. Its a very nice interior. What I don't love is how Android Auto is slowly breaking since it assumes more and more that you have a touchscreen.
It used to be that it would focus buttons in notifications, making it easy to interact with. Now the focus doesn't seem to change at all (or only sometimes) making it a nightmare to do simple things. I dare not use the new Gemini assistant since the last time I was completely unable to navigate to the buttons in its panel at all.
I really hope they don't phase out the wheel just because Google sucks at supporting it. I know they have both touch and the wheel in newer models now.
I cried when Mercedes go rid of the click wheel. Research in this article be damned, I’d argue that rotary knobs with directional shifting like Mercedes paired with great software are the best car infotainment interface in recent history for screens in cars.
I love voice control, have you tried/gotten used to that?
The reality is they want to serve us ads in the future. But they first need adoption.
Stellantis tried it already, had to back-pedal calling it a "glitch". I'm sure someone else will be bold enough to try again though.
(a) cars have forward-facing cameras/computer vision for lane tracking
(b) infotainment systems have always-on cellular internet connections
(c) billboard impression counts can be tied to the vehicle
IIRC infotainment systems are already showing ads in some form. And location + driving performance is being captured + monetized and shared with insurance companies.
Unless this results in an EV car that I can rent for less than $100/mo, this really needs to be stopped.
> But they first need adoption.
I think they've got that. Short of budget stuff or the Slate truck, most new cars have some big dumb screen in them at all times.
But advertising poses a new problem for both advertisers and mfgs not unlike the mid-90s ad sale issue. There was no consolidated ad server, so everyone was trying to build their own agency and advertisers had to navigate that.
Which probably means some sort of Google or Google-like player in the space.
I think that nowadays people value "technological features", and how better to show "technological advancement" like a giant ass touchscreen and not some "old" XX century knobs.
I hope that changes and people start valuing simplicity and robustness over electric gimmicks (I know many people already do, but we need critical mass).
It is so much easier to add internationalization to a touchscreen over physical buttons
How much is that needed? There was very little text on those buttons to begin with. Are there significant cultural differences in the iconography associated with them?
Sure, touchscreens are cheap, but high-quality touchscreen software is most def NOT CHEAP!
Apple and Google have spent untold amounts of money developing iOS and Android. CarPlay and Android Auto are really nice.
Tesla has spent gobs of money on its touchscreen software too. It's the only native car touchscreen UI I've tried that feels smooth, snappy, responsive, simple.
I've tried the native touchscreen UI of quite a few US and European carmakers. All of them fall short. They feel janky, clunky, obtuse.
Physical buttons are much, MUCH cheaper than high-quality touchscreen software.
I think the reality is that it is harder to sell a subscription to a button than it is to software.
Yeah, that's true. Sigh.
There has been more pushback on car screens over the past couple of years, and the optimist in me hopes this leads to change. With enough pushback, manufacturers will have to listen to the market, cost savings be damned.
A concrete step I take to push this along: I mention physical buttons as a dealbreaker to car dealerships when I shop. Of course, I'm only speaking to dealer reps and not the decision makers at $CAR_CO, but if enough people do this, it does get back to the them and will make a difference.
I could not imagine having to go back to buttons for anything I actually want to control. Once you get used to a well-designed touchscreen, buttons are just so clunky and unintuitive for most functions. Dials are probably my most favorite physical control, but other than volume there's not much it's useful for in a well-designed, modern car anymore. It was great for radio stations, but is terrible for Spotify.
Setting temperature manually by dial doesn't make sense anymore either- most cars have too many things to change and an expanding menu is great. There's hot cold, faster fan lower fan, feet vs head-height (we're already looking at more than three separate controls). Now there's seat heating and cooling (with varying power), steering wheel, defrost, controls of vent direction, etc.
I'll admit the touchscreen might be daunting if it's a rental but it takes like one week to get everything mapped out mentally (and going back to physical controls on rentals sucks).
That works as long as you actually stick to your guns and keep them as deal-breakers. If you accept them with some grumbling, that's still a sale and that provides no backpressure to the manufacturer.
In Europe it's done through EuroNCAP: https://etsc.eu/cars-will-need-buttons-not-just-touchscreens...
It has already started asking for physical buttons for key functions to give manufacturers the top safety rating, and it's working. Buttons are coming back.
Their source is "a Swedish motoring magazine in 2022". Europe sure does love regulation- no desire or call for finding the best way to implement vehicular controls, just a desire to lock in old functionality with a flimsy excuse.
My biggest issue with touchscreen controls is that they are not ergonomic.
1. Usually they are high on the dash, higher than where conventional controls would be
2. You cannot rest your hand on the surrounding panel to press them, because this will cause unintentional presses on other buttons
Resulting in two problems:
1. Because of the above, you must activate more muscles to steady your hand and arm in a moving car to accurately press them. This is less comfortable and leads to frustrating misclicks
2. This increases the amount of time required to use the controls, which is annoying for infotainment, but dangerous for anything safety related
Neither of those are a problem in my 2015 Tesla Model S for the buttons that control the climate control or media player.
It seems to me that many of the problems that people report related to touch controls are more to do with how they are laid out than the fact that they are touch controls.
The $6,000 profit per car referenced in the article is gross profit, not net profit. Net profit is considerably lower, around 5% for the mass manufacturers. So a $100 cost savings is very significant against a ~$3,000 net profit on a Bolt.
OP: ooooo, that's neat. Do you have a source? I struggled to find a source for even that $6,000 number.
I want to cheer (again) for my 2020 Ford Escape. Its infotainment design was a significant differentiator that led to my selection after testing a dozen different models across all US manufacturers.
It has Carplay/Android Auto, naturally, but it also has physical buttons for play/pause/previous/next and volume, and physical buttons for A/C control. All buttons have a single (sometimes dual) fixed purpose, they don't change purpose depending on whatever mode something is.
It is, in my mind, an ideal amount of buttons compared to, say, the Honda CRV or Toyota RAV4 at the time that had extra buttons around the screen for flexible features, meaning those buttons had no fixed purpose.
I hear the Escape was actually designed for the European market (as the Kuga), which may explain its design sensibility.
Unfortunately, the Escape has not been a roaring success, and Ford will discontinue it in the US market in favor of the Bronco Sport which has, you guessed it, a huge touchscreen and few physical buttons.
I gotta say, the one redeeming feature of Ferrari Luce, for me at least, was the interior. I don't dislike screens, I just hate the tesla-esque obsession (where, for them with FSD - for all the hate they get about it up here - it might actually make sense since u are gonna have a FSD+Grok car) with no buttons. I know buttons add cost, but going back to the Luce example again: you have a healthy sized screen (so u don't go to the pre-tesla days), but you also have wonderful buttons across the board.
Now, I know it's not a very representative car. But nobody said the buttons need to be as flashy or as numerous.
Tesla arguably has better, more useful, and more obvious physical buttons than most cars. Most car manufacturers spray confusing physical buttons everywhere with esoteric icons and insane UX. Everything you'd want to do as a driver in a Tesla has a physical button or a set it and forget it "auto" mode.
Uhm, I like Teslas a lot. The design and the philosophy of just minimizing the amount of components. But where I would draw the line is AC via touch screen (again, if Grok can now do it reliably, fine, otherwise, buttons please). Also, depending on the model, I know some models had turn signals in some weird places (above the head? or am I hallucinating?). Also to make your point: if it hadnt been for carplay and its android equivalent, legacy auto would have been cooked long ago. I never use my VW native apps.
My point being, I think we havent found the sweet spot yet.
That's why Lyft/Uber drivers who use Teslas need to cover them in stickers explaining how to do such esoteric behaviors as "open door"
For touchscreens, I think there is an opportunity to make larger touch targets. For example, when you want to adjust HVAC controls, the UI should take over the ENTIRE screen with ridiculously huge targets. Something in the range of 1-4 square inches in size for a core button should allow your for reduced cognitive overhead. This is critical for safe driving.
I think its easier to develop muscle memory to certain buttons. For instance I had a similar 1DIN head unit to the one pictured in the article. I never needed to look at it to operate it.
There was a study from a few years ago that associated almost all increase in traffic deaths in the past decade or so with in car displays. Almost all deaths were pedestrians being struck at or after twilight. The thinking is that infotainment systems are making drivers take their eyes off the road to adjust anything in their vehicles, and also ruining their nightvision. Not sure how they were able to separate this from smartphones.
As an engineer in R&D, I've always known if I needed a cheap but amazing part, to look at automotive replacements from third parties for parts to build an MVP with.
Those rear hatch motors are amazing and most have indexing.
I think there is a real market for modding news cars to have physical buttons again. Whenever this discussion pops up on the internet, there's plenty if people who prefer them (they're called "old folks" ;-)) so why not mod your dashboard to feature a - wait for it - volume button for your music!
I wonder how much can be controlled over some kind of bus. Would be cool to have all sorts of physical buttons and a micro controller to control radio, AC, heated seats etc etc so I can keep looking at the road while changing things.
The volume button (dial) broke on my Ford Maverick in summer. Moving to a touchscreen car felt like a sigh of relief that I no longer had to worry about buttons and dials breaking when I need to use them, and don't have to worry about a trip to a dealer or tearing apart a dash to replace them. I will say a button "feels" nicer, but the added risk to me wasn't worth it. To each their own
Yeah, wait until the whole thing is unresponsive due to heat or a bug, you’ll be wishing only your volume button was affected.
The fact you can rip open the dashboard and fix something is great and what I call a feature, not a bug.
Or you reach for a certain area of the screen out of muscle memory, but the UI changed "just because" and now you're very distracted.
> wait until the whole thing is unresponsive due to heat or a bug
Chances are if the whole thing is unresponsive due to heat or a bug the volume knob isn't going to actually change the volume as well. Its not like the knob is the actual pot directly changing the circuitry in the amp these days, its a digital input.
Not convinced that is true.
I've personally experienced it on at least six different car infotainment systems by four different manufacturers where the stereo will start playing whatever was left on, you turn the volume knob but the whole thing is still loading so it doesn't react for a few seconds.
Even outside of OEM head units, I've owned a few after market head unit stereos where the volume knob was technically a digital input and if the system was lagging hard the volume input could be delayed a good bit.
A number of these systems will have a different volume level for things like phone calls than for the music, but both volume levels are controlled by the knob. It'll also do things like automatically lower the volume level for notifications or have dynamic volume levels based on acceleration. The knob is rarely directly controlling the actual output of the system.
Here's a good question: if you press the volume buttons on the steering wheel controls, does the volume knob on the radio move?
This company sells buttons for Teslas: https://www.enhauto.com/pages/buttons
The "cloud features included" line amuses me greatly given the low-tech theme.
Here's another really nice looking one: https://www.ctrl-bar.com/ Mine is scheduled to be delivered tomorrow...
car touchescreens are in the same category of most laptop webcams/cams: just make it good enough, and make it fit (and they both suck, most of the time)
Car touchscreens are a safety hazzard. Everyone hates them (except tesla owners), they need to largely banned
Just ask the car, unfortunately, asking rarely works unless you're in a Tesla.
If we ever get flying cars, I hope they have real buttons. I imagine it's too late for land cars to ever go all the way back to buttons.
Maybe people should stop buying cars with crappy touch screens then? The touchscreens in my Model 3 has been amazing. Ever since I took delivery of it in 2019. Manufactures need to do better.
I hate the way climate controls take over the whole screen, causing me to lose my map screen.
Voice interface is the future, just have voice assistant do everything without relying on knobs nor touch screen
same way people just talk to claude code via whisper
Lordy I hope not. Cannot imagine having to childproof my car's entertainment system, or make sure I don't sing a trigger word, or try to turn on the defroster to dehumidify the windshield during an intense rain storm where I can barely hear myself think.
Also: I don't want a microphone in my car at all times. Thank you.
It could use array microphone to detect that the sound originates from the driver's seat (in addition to using it for filtering out not-from-driver's-seat sounds).
I mean that's cool, if it actually works reliably. Automation tech enthusiasts are willing to be impressed by 99% reliability. To get buy-in from regular people, it needs to just work better. To be clear, I don't know how reliable this actually is now, but I'd be willing to bet that it's not reliable enough.
Hell no. I'd sooner tear out my own vocal cords than accept this future.
No. No, please, no. I won't buy a car that relies on voice for anything, and I really don't want to rent one either. Wildly inefficient, slow, unpredictable.
