Tesla touchscreen wiper controls land driver with fine after crash

Any car you are in is traveling with kinetic energy, so it is likely to bounce and move around over the road surface. Without a physical button to rest your finger on it's nearly impossible to get something on the first "touch" unless you are standing still.
Yes it looks cool, and yes it's fun to play with on a red light, but using any of these touchscreens even at 50 mph is nearly impossible.
Made much worse if it's a sports car and has a bit of a stiffer suspension.
One step forward, two steps backwards.
The manual controls on the screen even pop open when you hit the button, so its just one tap of the screen to adjust the speed.
However this makes me wonder: is it still cheaper when using a large expensive panel like Tesla does? And even if so, what place do such cost-cutting measures have in [ostensibly] luxury vehicles?
1) Tesla's panel is not expensive. For a long time (maybe still), it wasn't automotive grade (rated for high temperature and shock/crash-proof operation) - they just used a standard consumer panel - bulk cost likely well under $300. For comparison, that's about the same cost as a traditional automotive head unit alone. Other items not included in a model 3 are also not cheap - for example, a standard wiper switch assembly is about $25 since it's fairly complicated and has pretty high QA standards. A standard instrument cluster is going to be close to $100.
2) You have to consider manufacturing cost, not just parts cost. Wiring is a huge pain in the ass on an assembly line since it's very difficult to automate and it's easy to mess up, so the more things you have to wire to different places in the cabin, the more labor time you have to pay for. Running everything via a single screen means you only have to wire components to the CAN bus and can drop a lot of the usual driver controls wiring harness pain.
3) The HN crowd is not indicative of the wider market. I learned this the hard way when working on an LCD-hard button hybrid interface for head unit controls. A lot of customers (maybe even most) absolutely love touch screens and think the Tesla central panel is fantastic. For them, an all-touch central interface is a marketing win rather than a drawback that needs to be explained away as a cost cutting measure. Model 3 is not targeted at older, high-end luxury vehicle buyers, it's targeted at environmentally conscious tech enthusiasts with a decent amount of cash and a bit of a craving for status signalling. If you draw a venn diagram, there's a pretty big overlap between this segment and the "wants touch controls" segment.
But then, #2, you factor in the cost savings associated with simplified manufacturing (which, as GP explains, goes well beyond just the wiper switch). This is what makes the panel approach much cheaper.
To me, the much more plausible aspect of the explanation is they think it looks cool/futuristic and their buyers are buying for reasons other than usability.
I'd also point out that Tesla is hardly the only automaker that is increasing its use of a single touchscreen for these functions. And, before that, manufacturers were already combining features into all-in-one units that were very similar in principle but controlled in different ways--such as with weird knobs, and other things. I expect it's a combination of consumer "wow factor"--which will probably wear off very soon--and streamlined manufacturing that drives this. But I'm no expert.
For the wipers specifically, putting it in the screen is questionable for safety reasons. The rest of it definitely saves them money.
And to your other comment, please look up bulk touchscreen panel prices on Alibaba. They are far cheaper than you seem to think, especially since the majority of the computing power is in a separate module. The model 3 uses the LG LA154WU1-SL01 panel. It is not expensive (under $300 in bulk) and continues to get cheaper.

Other competitors are willing to sacrifice those details in order to undercut Honda (also note the mirror and window controls): https://newchevy2020.com/wp-content/uploads/2019/10/2021-Che...
The Spark starts at $1700 under the price of the Fit.
It definitely doesn't have cruise or lane keep assist.
Tesla used non automotive-grade panels to keep costs really low. They started delaminating and the solution was to have everyone's cars run the air conditioner even when the car is unoccupied, causing a big negative impact on effective mileage in the city, but it actually got great response from fans with slick marketing around it. It saved Tesla a lot of money in recalls, but is not great environmentally.
And it isn't all about the customer. Would one of these teslas survived on a used car lot? Could it survive being transported across the country on the back of a truck? A car that cannot survive direct sunlight is a logistical nightmare.
Where a traditional design would have taken care to run entirely from a read-only storage, and if there is logging needed, to log to an extra partition that doesn't stop the system from working if it becomes unavailable.
Apart from that, it also has this feature that makes using the touchscreen for the wipers while driving completely unnecessary (when they're on "automatic"): https://youtu.be/1Rr_XzzJ6gc?t=58
Finally, there's also voice controls: "Wipers increase" and you're done.
It's not magic, the horrible thing we still have is courts with clueless/uninterested judges.
> The Tesla Model 3 automatically adjusts the speed of the wipers depending on how heavy its sensors believe the rain is. > It can be switched on and off from the steering wheel, but adjusting the interval needs to be done on the touchscreen.
And, more relevant:
> ...the driver complained to the higher regional court. Windscreen wiper control was, he argued, a safety-related feature that he needed to access.
Your attack on "judges" is misplaced too:
> The higher court disagreed, backing the first judgement. Whether or not the screen was a permanent part of the car was irrelevant, it decided - and it did not matter why the driver was looking at a touchscreen while driving, only that he did so.
I'm not saying you are, but from your comment it really seems you did not read the article and only rushed into the comments to defend Tesla.
If the driver had used voice control he would not have been fined.
> It's not magic, the horrible thing we still have is courts with clueless/uninterested judges.
In Germany, judges are supposed to apply existing laws, not to amend or alter them based on their "clues" and "interests".
They are also required to honor the original intent behind the law and that was to prevent distraction from mobile phones and similar devices, not from vehicle controls.
The judge is not ruling about the UI/UX or Tesla or the car, only that the driver chose or allowed himself to be distracted and become a danger. You seem to agree that it's the driver's fucking problem to learn how to use the car without becoming a danger, so why would you then go insult the judge?
The driver fiddled with the touchscreen and caused a crash, and was punished for that. So you are saying the driver shouldn't have been punished for fiddling with the touchscreen because he didn't have to use the touchscreen? Wouldn't that be a bigger reason to think the driver is at fault?
If you want a single wipe, you can press the button on the steering wheel controls. This would also bring up the touchscreen menu for wiper speed directly, for a 1-touch change. Or 2-touch, if you count the steering wheel stalk button press.
The same as when people buy power cars which are difficult to drive without training and then oversteer and crash.
There is a huge difference between a radio and a wiper control. Wipers are not some optional thing you can ignore for a while, they’re essential for safe driving and should be accessible to the driver without distraction.
Then you turn on the wipers with the button on the stalk, like most cars.
If you can no longer see due to rain, stop the car.
Your first priority is to keep the car safely on the road and not run into any obstacle. Everything else takes second priority. If you fail to do that, you’ve failed your task as driver, you most likely were too fast.
This US-like transfer of responsibility to more and more overbearing regulators (and regulating corporations like Apple/Google/et. al.) has always seemed very harmful to me.
However it could indeed lead to mandatory safety standards requiring physical controls.
"When you need to adjust car controls don't forget: Pull to the side of the road."
The buttons etc are designed for a car that can run the wipers etc flawlessly itself but the tech isn’t there yet.
This is probably why CarPlay and Android Auto still aren’t integrated, among other reasons.
This is why all companies are moving eveything to touchscreens - the cost savings are very real when it comes to building a certain amount of units in certain amount of time. And this is why the company with most manufacturing issues, Tesla, also went all in in making the cockpit as minimal as possible.
Sure there might be other reasons, but as always... follow the money :)
It's just their design goals are not "make the most convenient or practical control we can"
They're "make it cheap to manufacture" "make it easy to manufacture" and "make it perpetuate the vague feeling of futurism we go for"
The giant touch screen is at the intersection of all three. It's truly awful, but people convince themselves "this is the future!". And they say stuff like "I can't imagine going back to anything else" because by comparison the buttons feel dreary and old.
Then to keep up other manufacturers start to follow suite and now even pickup trucks are bragging about having 12 inch touch screens in their advertisements and how the competing truck doesn't ...
Just kidding! But, my assumption is that an engineer isn't the one making design decisions about the touchscreen UI at Tesla.
I'd go so far as to guess that the decision to move every possible control from the dashboard into software might have come from the top of the org chart, or near it. I have no idea if it's true, but it feels like one of those "visionary leader" decisions made by someone with little accountability and a lot of Dunning-Kruger.
Along with a voice operated climate control, you don't need to touch the screen, ever
Second... are you kidding me?!
A driver deciding to look down at their screen to share media while driving would be blamed... on the infotainment, is that a joke?
By that logic you're also allowed to look down at your cupholder and count the crumbs that have accumulated, that's a terrible design and the cupholder should be mounted at your sightlines.

Normally I'm in the "putting screens in is adding unnecessary temptation" camp, but please.
Personal culpability is still a concept.
MB kept all the stalks that make sense, they kept the steering wheel buttons, they kept physical buttons for stuff specific screens. They did fine for the parameters they're playing with, which is "Tesla has made not sticking a giant touchscreen in your car not seem futuristic".
"Almost" is to say that no, it's not enough. Show me climate controls on the steering wheel.
> Along with a voice operated climate control
No. A very very small minority of people operate anything via voice control. Especially in cars where voice control is universally horrendous.
Same with the console mounted touchpad.
Both of which don't require the level of coordination touching a touchscreen would require.
There's also the fact they're giving people what they wanted, voice control suck but that's how you make it work with a giant touch screen, and people's buying habits and feedback on Teslas have shown it's what they want.
It wasn't until last year Tesla's voice input was even doing natural language-ish stuff. MBUX meets the (low) bar that's been set.
Riiight. And to see where exactly you are on the screen you need... guess what, look at it.
> There's also the fact they're giving people what they wanted, voice control suck but that's how you make it work with a giant touch screen
Yup. You got it all backwards.
- They install a huge touchscreen with horrible controls
- These controls are incredibly bad, and are a hazard when the car is in motion
- Instead of fixing the horrendous UX, they patch it with voice control
- Voice control, by your own admission, sucks
So, no, they are not giving people what the want. People want sane and safe controls inside a car. A huge touchscreen with no physical buttons, tiny controls and touch targets, and a voice control that sucks is not what people want.
> MBUX meets the (low) bar that's been set.
How about raising the bar instead of leaving it on the ground?
If your cognitive functions are a limiting factor, sure?
One of my cars has a touch screen and a knob to control it. It took my about 2 days of owning the car to know how many knob clicks to get to "Change input".
At worst I might glance at it for a second if I overshoot by an item, no different than when we had individual knobs for everything and you might occasionally glance to see how far you turned the knob

Also, maybe read things twice.
> voice control suck but that's how you make it work with a giant touch screen
Read that again, slowly.
It means that they add a touch screen and make it work by patching in voice. You didn't need to repeat my point for me.
-
Your problem is you think this is some sort of debate where I'm backing "Team Big Touchscreen And Voice Controls" and you're going "aha! Gotcha! You don't like voice either!"
No. I don't. But you're wrong, people do want touchscreens and crappy voice controls, and Tesla's cult following is proof.
That garbage interior is hailed as futuristic over it's tablet, and everyone is following them because, despite your illusion that what you want is what everyone wants .. people like the idea of a big shiny touch screen in their car to make it "futuristic", that's why people end ip retrofitting 12 inch screens into their 10 year old Camry now.
MBUX is above the bar that's been set in useability, but they don't set the bar because they don't have the image or mind share to do so. If tomorrow morning Tesla removed the screen and replaces it with AR goggles I promise you that will be the new bar.
> maybe read things twice.
> Read that again, slowly.
Ad hominem attacks, how nice.
> they add a touch screen and make it work by patching in voice.
Exactly. What I said: they made a horrible UX, and then patched it by adding more horrible UX. It's decidedly not what consumers want.
> people do want touchscreens and crappy voice controls,
Nope, people don't want that. But they are left no choice.
> MBUX is above the bar that's been set in useability, but they don't set the bar because they don't have the image or mind share to do so.
Because they are blind following the one-eyed, that's what you're saying. It does cost extra money and extra care to create a workable touch-screen experience that doesn't rely on "but there are tiny buttons on the wheel and voice controls". Volvo can do that (even though their touch screens are far from perfect), why can't Mercedez?
Oh, right, how can one forget, because horrible UX is "what people want because that's the bar". Cry me a river.
Edit. It's actually amazing that they have a 23-minute overview in a static non-moving car [1], and they keep
- doing accidental touches
- inputing wrong commands
- being very-very careful and precise with what they touch on screen because all the touch targets are so small
In a non-moving car. It's amazing, really, in a horrendous kind of way.
You'll understand that the crux of your misunderstanding, which I've clarified twice now is:
> they made a horrible UX, and then patched it by adding more horrible UX. It's decidedly not what consumers want.
It is what they want.
Go and look at which automaker is worth almost 1.5x Toyota's market cap after launching a car that gets you fined for changing your wiper speed since it's all on a touch screen.
Go look at which car people tout as the most futuristic.
Go look at which interior is shown rubbing shoulders with Bentleys in interior design rankings: https://www.roadandtrack.com/new-cars/g22496899/best-new-car...
See which car everyone drools over setting the bar for form and function: https://www.businessinsider.com/tesla-model-3-interior-is-a-...
I mean seriously, you'd have to be blind to not see that automakers are now chasing Tesla because people have convinced themselves, maybe through Musk's charisma or some misguided aspiration that this is the future:

I said it very plainly, you seem unable to divorce your personal preferences and views from reality of what people want.
I hate the giant touchscreens but that doesn't mean I'm going to ignore the fact people rant and rave about the interior that started this trend.
It also doesn't mean I'm not going to give credit where due as a manufacturer kowtows to demands, but manages to pull some additional function out of the burning wreckage that is now "what is in, in car UX".
Maybe if you read my comments through that lens instead of acting like this is some kind of high school debate team practice, you'll finally understand why I'm saying you're missing my point (repeatedly).
Safety controls aren’t something that should be subject to “move fast and break things.”
My Dodge truck has much better automatic wiper control than my Tesla.
I wouldn't have guessed.
Touch screens are a much worse interface that physical interfaces in many cases, especially when you are driving. I don't understand why you would take away almost all feedback and speed from some control, and consider it progress.
- The main mode of use is 'auto' which uses as its feedback sensor the forward facing camera (I think only this location, but not 100% sure about that) located where the rear view mirror attaches to the wind screen. It covers ~75% of my driving without issue. I think there is a problem with that sensor location as the boundary layer gets compressed near the apex of the windscreen, resulting in better mass transport and a drier windscreen than the part the driver looks through. This camera location is thus a laggy indicator of rain because it tends to be one of the driest parts of the car. Personally my experience with the this feature is a good advertisement not to get full self driving yet: If you can only answer the question "Is it raining?" accurately 75% of the time with cameras, you've probably got a long way to go on FSD.
- There is a physical button on the end of the left stalk. You press it to get 'wipe once'. If you need to respond quickly to a sudden burst of rain or the driver next to you goes through a big puddle, you can do that without the touchscreen.
- The physical button push also brings up the wiper control on the touchscreen, which is otherwise behind one (non physical) button which is always on the screen. The touchscreen controls include manual control of wipers on/off/auto and wiper speed.
- There is also voice control which seems to work fine. As with many voice control systems, you have to say a specific phrase, which presents a discovery problem: how do users learn that phrase unless they're the kind of people who search out documentation on the internet. I'd also wager many drivers haven't gotten used to the idea of voice control of car features so they're not well utilized in general.
And for your consideration, my opinion: It works fine most of the time (because I just leave it in auto), but I occasionally need to tap the physical button to get an extra wipe. Sometimes when it is very lightly raining I need to manually set the speed since the feedback system doesn't seem to do a good job in that scenario. The touchscreen feels pretty accurate and responsive, so I've never had trouble hitting the button while in motion. I think Tesla should release a software update to let the user 'double tap' the physical button to force the wipers 'on-high' for the rest of the journey.
The internet? The car doesn't come with a manual? Doesn't _every_ car come with a manual?
If the vehicle is _road legal_ (that is it has stop lights, breaks etc) then it is assumed that it can be used legally on public road. If the touch interface would make the driver break some laws then the vehicle should _not_ be road legal in the first place.
It looks like Tesla's job postings reference ISO 26262 experience as a plus [2], but I can't get a straight answer to Tesla's adherence to it in-house. My understanding is that no government mandates its use, but lots of car companies adopt it anyway.
[1] ISO 26262-3:2011(E) Table B.4 [2] https://www.tesla.com/careers/job/software-integrationengine...
One way to improve it would be after the left stocks quick wipe button is pressed, let us adjust the speed with the steering wheel control wheel with a volume based auditory click to indicate it's gone up or down. Although those are used for volume and speed if cruise or autopilot is enables so it would need to only stay in wiper speed adjust for a few seconds
Just as short as checking whether I got a text message?
I always assumed there was some rigorous usability test they’re required to undergo.
It’s better with physical touch controls to control car functions.
Consider search depth, physical device control is direct access hash table. But touch button interfaces are like searching through a list/tree so slower.
Provide essential info and control in the simplest possible manner. If you feel the need for additional gadgetry, use voice recognition and response --- something with minimal distraction from the essential task at hand.
These headline-esque sentences are very hard to parse without context sometimes. It took me ages to figure out this one. It's a small hobby of mine.
But don't worry, it's fine. It was not damaged in the crash.
(By the way, we're in 2020. Weren't we supossed to get self-driving cars without pedals and steering wheels by now?)
No need for knobs.
I agree the wiper controls could be better though. Would be great if a combination of the wiper button + scroll wheel could change the interval.
"Tesla, slow down the wipers."
The voice recognition is a bit sub-par IMO, but I can control the wipers by voice if I want.
