I know people on HN make a big deal over this and it’s easy to make an argument for tactile buttons, but when it’s a quality interface (like on a Tesla) it’s really a non-issue.

It reminds me of the complaining in the early iPhone days about lack of a physical keyboard.

I totally get that. People will always complain about some new design fad, whether it's actually good or not.

However... we're talking about heavy vehicles traveling at high speed with humans inside. You simply don't have to takes your eyes off the road as long with tactile controls as you do with touch screens.

Having driven a Tesla for three years now, I basically don’t use the screen while driving. The controls I actually use are on the steering wheel or column (cruise control settings, music control, turn signals) and I have never had a significant issue with leaving wipers, lights and climate on auto

I mostly agree, but it's that time of year again when I question my life choices. The rain has started, and suddenly I'm reminded how stupid the wipers can be. Elon keeps promising over and over that they're just about to fix them, but it never happens. It absolutely will be a factor in whether I buy another Tesla.

My only experience with touchscreen cars is with the Model 3. You don't need the screen for operational stuff needed for driving. Off the top of my head, these are all on the steering wheel/stalks:

- Blinkers

- High beams

- Gearbox

- Climate control temperature up/down

- Cruise control enable/disable, speed change

- Media volume, media next/previous

- Phone call answer/hangup/volume

- Windshield wipers

On the next Model 3 version, they are moving the gearbox controls over to the screen. I have my doubts about that, but I'll complain once I have driven one.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by loueed on Wednesday September 06, 2023 @11:27AM (#37406536)
From what I've seen, they include a fallback set of gear shifter buttons below the centre console. These work even if the screen is black.

I do see a lot of praise for its ability to auto shift, basically it should predict the direction of the vehicle based on the surrounding environment.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by liminalsunset on Wednesday September 06, 2023 @11:57AM (#37406994)
The primary issue with the touch screen in the Model 3 in my opinion, is actually the climate controls. You could argue that these aren't necessary to adjust while driving because the car is supposed to do it automatically, and/or you can use the admittedly terrible voice command system, but things like the recirculate button (I know I'm not the only one that uses it, my friend keeps tapping the physical button in his Honda and doesn't have to look at it to do this) are particularly annoying.The climate controls are in a drawer that is opened by a swipe up, and until the latest update, the recirculate button would highlight but not activate/toggle if pressed slightly off centre.

The other situations involving wipers are also annoying when the auto windshield wiper sensor becomes invisibly dirty. The wipers will activate nonstop during Autopilot or just on auto while driving in daylight sun, particularly at sunrise and sunset. It is an extreme frustration to have to look at the screen to click the slider to turn them off.

As of the current software version, the way the buttons on the stalk or the wheel work is they either activate something one off e.g. high beams for a moment, or wipe once, and/or they pop up a little menu on the bottom left corner of the screen where the media controls are, and you have to use the touchscreen to activate them. Recently a mechanism to press and hold the steering wheel scrollwheel to activate a menu was added, but it's just impossible to use without looking. I am not sure if I am special and/or are using it wrong or something, but the menu pops up in a location that is obscured normally by my arm/the wheel when holding the steering wheel at a normal and designed position with both hands. Annoyingly, this is also where the "Apply slight turning force to steering wheel" nag prompt appears, which is a terrible and unnoticeable place to put a safety related alert that is actually designed to have you keep your eyes on the road. This really should have the option to be an audible and friendly chime.

The lack of a turn signal sound when the computer crashes, is, by the way, another omission in my opinion, because the turn signal stalk is only a momentary button. The turn signals work but you'll have no clue while driving if they're actually on, without the screen and the sound.

I mean, maybe these are all normal and maybe I'm just really picky about things. I really do like the overall experience of using the large screen, as the GPS is much more glanceable with this setup and passengers can route plan or discuss the route. The apps are all terrible though, like Spotify/Apple Music, and they're unnecessarily slow and buggy with small touch targets as if they want to trick you into keeping your eyes off the road for more than a fraction of a second.

The UI design is kind of mixed, tbh. I'm sure some of these issues can be resolved by software, but at least there are the "S3XY Buttons", a third party accessories with a set of BLE buttons that you can stick anywhere you like that activate things using CAN bus injection.

Of course, that might (not sure, dont have this accessory) create synchronization bugs like (annoyingly, sometimes the car saying it is in reverse when it is in drive), but these happen anyway by itself.

No need. Push the button on the left stalk, press the left scroll wheel to the left for a couple of seconds.

I have mine configured for climate control temperature. I don't look at the screen. Long press, two clicks up or two clicks down.

> The lack of a turn signal sound when the computer crashes

If you mean that the turn signal has no sound, you are mistaken. The turn signal has a sound. I have no idea, though, if it sounds when the computer crashes; mine never did.

That's great that Tesla puts those (physical) controls on the steering wheel.

But, think about this comment in context.

As a reminder: I was replying to someone who was arguing that the anti-touch-screen crowd is not justified in their hatred of touch screens in cars. My position is to agree with that crowd that touch screens in cars are bad UX.

With that in mind, your comment actually vindicates my position. Touch screens are dangerously stupid UX in a car. So much so that Tesla--which has an image of being futuristic, sleek, and minimal (aesthetically)--not only has the necessary-for-driving controls on the steering wheel, but also non-essentials like media controls. If touch screens weren't objectively worse than physical controls, is it too far of a stretch to think that Mr. Musk would've wanted them in the touch screen for even more sleekness and minimalism?

In any case, I think we're all agreeing in this thread that touch controls for these things would be unsafe and worse than physical controls.

The case now needs to be argued that touch screens are at least equally good as physical controls for those other operations in cars. But, I don't see how that line of argumentation can possibly go well after we've established that the important controls don't belong as touch buttons.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by sergiosgc on Thursday September 07, 2023 @11:39AM (#37420586)
Physical knobs and buttons are great for muscle memory. How much of a muscle memory do you have for the controls setting mirror position? For setting fade/balance on the stereo? Enabling valet mode?

The UI question is only valid for controls used frequently. For everything else, I think it is already settled that they are better in the screen. At the very least, for the sake of UI simplicity. I can't imagine a physical interface for enabling or disabling every driving assistance option in a Tesla. It'd become an airliner button panel.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by ragnese on Thursday September 07, 2023 @02:38PM (#37423585)
Fair point. We don't need dedicated, physical, buttons for infrequent or unimportant things.

But, to be fair, I don't think that most people who vocally hate touch screens in cars are upset that the car manufacturers are making them set their clock via touch buttons. I assume (and I could be wrong) that they're talking about things like A/C settings, radio tuning, etc. If they aren't, then at least I am. Being able to reach over with my muscle memory to change the radio to one of my presets (yeah, I'm some old-school weirdo who still listens to FM radio when I drive) is something I appreciate.

There's a gigantic difference. You stare at a handheld device when typing. When you're driving you need to feel what you're touching, otherwise you have to take your eyes off the road.

Physical button are superior. At least to me obviously.

This is so not the same thing.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by fossuser on Wednesday September 06, 2023 @11:28AM (#37406557)
It really is imo. Good touchscreen UI is superior in many ways (though not all) to fixed control buttons. It’s why it dominates phones and why it’s winning in the market for cars as well (Model Y was top selling car on earth for Q1 2023).

Bad touchscreen UIs suck, but that’s also true of phones. Good tactile controls have some advantages, but ultimately they’re minor and worse on net than a good touchscreen interface.

People on HN will disagree (like people here disagree about everything), but the market will settle it.

The iPhone works because it's a device you'll look at all the time while operating its touchscreen.

The car touchscreen doesn't work since you need to operate buttons without directly looking at them, purely by tactile feel.

This is not a problem touchscreens we're able to fix so far, and I don't think this will change any time soon since there's just not enough ways for a touchscreen to provide this level of tactile feedback.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by HumblyTossed on Wednesday September 06, 2023 @12:22PM (#37407347)
>It really is imo.

It really is not IMO.

A touchscreen UI is a visual medium. That is not what you want/need while operating a vehicle. You should be able to change the AC by feeling for the button and not taking your eyes off the road.

This isn't just HN being HN again. Driving enthusiasts are pushing back on touchscreens.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by fossuser on Wednesday September 06, 2023 @12:47PM (#37407663)
I'd bet most people look at the tactile buttons when adjusting them, to see the temperature, fanspeed, etc. and that the difference between this and swiping on the tesla display isn't an important difference.
Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by HumblyTossed on Wednesday September 06, 2023 @12:51PM (#37407718)
I bet they don't. Muscle memory is a thing. Do you look down at your blinker lever to change it? How about your wipers? If you have controls on your steering wheel, do you look at those to press them?

I bet not.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by fossuser on Wednesday September 06, 2023 @01:36PM (#37408307)
The stuff on the steering wheel no, but the stuff on the dash (radio, aircon, fan, etc.) I did look at when I had tactile controls (this is primarily the stuff that's moved to the touchscreen, the wheel controls/levers let you do tactile actions without looking for more common stuff).
Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by rootusrootus on Wednesday September 06, 2023 @01:58PM (#37408654)
I'd take that bet. The only controls I use muscle memory for are some of the steering wheel buttons (not all, e.g. I still have to look for the cruise control on/off for my F250) and the stalks. And even then, when I switch between cars I sometimes have to glance to remind myself which functionality the right stalk has. For climate controls and such, I pretty much always glance. The only knob I can reliably hit without a glance is the volume.

Maybe I've just been driving so long that the variety of cars has impeded my ability to develop muscle memory. But I doubt it.

I was riding in a friend’s Tesla where the screen crashed while we were on the road. Just a black screen for some amount of time and had zero insight into the state of the car.

That just does not happen with physical controls.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by Zetobal on Wednesday September 06, 2023 @11:26AM (#37406528)
Eh... electronic instrument clusters had their kremlins before Tesla and touchscreens came around. The problem is the Software I've seen the source and architecture of the Mercedes cluster and infotainment systems and it's horrible glued together. You just see that QT wasn't made for the usecase.
Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by Kirby64 on Wednesday September 06, 2023 @11:54AM (#37406939)
Sure it does. Gauges are almost all driven electrically these days and not directly connected to a speed readout mechanically. If you have a problem with the gauge cluster, it's very common to have gauges malfunction. Sometimes they read incorrectly. Sometimes they read 0. If it's one of those multifunction displays, you could just have that display "crash" too.
Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by 0cf8612b2e1e on Wednesday September 06, 2023 @12:01PM (#37407035)
There is still going to be significantly better isolation than if it is all behind one pane of glass. If the radio is on the fritz, the hard-wired speedometer and windshield wipers should still be able to operate and accept commands.
Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by rootusrootus on Wednesday September 06, 2023 @01:56PM (#37408626)
A modern digital cluster is pretty much all operated off one little computer. Nobody's used hard wired speedometers in probably 20 years or more. And I can tell you that even back when we did have such things, it wasn't unheard of for the cluster to freak out. Had a ground wire crack on my '95 car and the gauges all started making very random readings. Some even looked plausible at first glance, which meant it took two trips to the dealer before they realized it was an electrical problem and not an actual malfunctioning cooling system.

In the case of the Tesla, BTW, the infotainment is 100% separate from the computer that controls the car. E.g. you loose the turn signal sounds, but the signals themselves work, etc. AP will continue to function, but you can't turn it on without the infotainment screen running. You can reboot the infotainment as you're driving down the street without it affecting your control of the car.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by saltcured on Wednesday September 06, 2023 @05:59PM (#37411968)
Reminds me of when my then-new '98 (or was it '99?) Audi A4 cluster partially crapped out on the highway. The needles dropped to zero and several warning lights came on, but the car still drove normally.

I pulled over and called the dealer service department for advice, and we decided it was safe (for the car) to continue my journey. But with the partial instrumentation failure, the air-conditioning also refused to operate, so I had a sweaty summertime trip.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by mohaine on Wednesday September 06, 2023 @12:08PM (#37407145)
Physical controls are just inputs to some computer in the car. The risk of a reboot is still there and I'm guessing on many newer cars, the computer the physical controls is wired to is actually the same one that controls the touch screen. This would be needed so you can control the same item via voice/remote app, even if you never use this.

I was driving a car once where the handle to the stick shift literally popped off in my hand. So... no, that's just silly. Stuff breaks. Important stuff breaks. You deal with that with careful design and redundancy[1], not whining on the internet about touchscreens.

[1] Like how in the Tesla all the driving controls are, in fact, NOT connected to the touchscreen controlled by the MCU but to the AP computer.

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by ghaff on Wednesday September 06, 2023 @10:48AM (#37405984)
There's probably some truth in that. Admittedly, it's a self-selected group to some extent, but the couple people I know who own Teslas basically tell me the controls are fine.

The reality is also that, in my Honda, a bunch of the buttons that aren't on the steering wheel/column are things I touch once in a blue moon and there are probably buttons I haven't touched since I initially set up the car.

And I don't actually want to navigate using my phone which is precariously hanging off an air vent using some some accessory clamp. Or by all means go old school and navigate using a map open in your lap.

(That said, I do think a lot of car manufacturers should be more thoughtful about preserving certain tactile controls however.)

Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by ghostpepper on Wednesday September 06, 2023 @11:27AM (#37406548)
Even if the controls are "fine" that doesn't mean they're not worse than physical controls. Just because they haven't caused a problem yet doesn't mean they won't under less than ideal conditions.
Re:If You’ve Got a New Car, It’s a Data Privacy Nightmare by ghaff on Wednesday September 06, 2023 @11:43AM (#37406767)
I guess it depends? If it's something I fiddle with all the time while moving (volume, wipers, lights, etc.) then sure. (Though does anyone put those controls on the touchscreen?) Probably environmental. But lots of settings are basically set and forget. My car has physical buttons for various modes that I rarely touch and would likely never touch while driving at speed.

The entire reason for touchscreens weren't because touch is better than tactile, it's because different apps will have different UI needs that cannot be predicted by the phones manufacturer. Steve Jobs says as much in the original keynote.

Cars don't really have this problem because they only have one primary job, and all other functions (eg climate control) are easily predicted by the manufacturer.
