It's probably true that once you (more or less) need a screen for a decent backup camera and most people like a screen for at least GPS, it must be pretty tempting to at least think about what physical buttons can reasonably be eliminated given that the touchscreen is a given. And I do think a lot of designs go too far.
personal anecdotes, but the vast majority of me being a passenger to someone else's driving, they all used their mobile device for GPS. even the couple of cars i owned that had a nav system, the GPS came from the mobile device. it required their app to be installed to input the destination, making the internal unit just a second screen for your mobile.
From my experience with two cars with factory nav, it's nice because it will show the next instructions in the the dash area, so when you're looking down to check speed you also get that. And, one of my cars has an option to show the next several instructions (Ford Sync2, which everybody hates because the UI is really slow, and kind of ugly). On the other hand, pay to play for data updates sucks. And most importantly, safety requirements mean you either have to yell at the car and deal with dated voice recognition or stop to adjust things; even if you have a responsible passenger who could use the touch screen.
Mostly, I just use my phone. It's simpler and faster. My cars are too old for carplay/android auto, and my experience with android auto was that it was worse than the phone in a clip or a cupholder, but carplay seems nice. For longer drives to unfamiliar places, I'll put the address in the car too, sometimes the phone gets tired of listening to GPS.
I was recently driving to visit a friend near Mt Baker, WA. and about 10 miles out, in a not particularly wooded area, the phone said 'lost GPS signal' and just assumed I had stopped moving, and wasn't able to pick up GPS again for the rest of the drive. Not a huge deal, because I was just following the road and only had one last turn to make, and I had directions from the car's nav anyway.
GPS seemed to work ok on the return trip. And I was getting an LTE signal for most of the drive too (gets pretty spotty at my friend's house, but I was streaming music when the GPS stopped, and that kept working)
Sorry, I don't have a debugging tale here; almost all of my excursions into figuring out why an Android device is doing something wrong leave me wondering if the device is doing anything right, and usually without any more insight into the original problem. Not going to try to do it, unless it's important, and probably not on a vacation.
so you're one of those that likes to make cute and endearing backstories to give sympathy to an inanimate object rather than getting irate at a mechanical something that you pay a monthly service not working correctly because the thing to get mad at is out of your realm of control and that anger serve no purpose.
I use CarPlay if I'm actually navigating, not the built-in Garmin. But it's an improvement over looking at the phone awkwardly clamped to an air vent.
I suspect most people don't use most of the native manufacturer apps even if they sort of need to provide them. Aside from rarely changing some settings, my touchscreen is mostly just a screen.
That's because in car GPS tech has historically been absolutely atrocious. An example: 2008-2012ish Toyota Camrys had a GPS system that used a DVD for map data. Not only was it out of date immediately (and cost $150 per new DVD from the dealer), it was insanely slow.
Nowadays, there's a few companies that actually seem to do a decent job of GPS in the car itself: Mercedes has a good tech in their new EVs that seems smooth. Android automotive (not auto) cars have built in Google maps such as Polestar, the new Cadillac EVs, and some other Chevy products do well. Although it's not much different than just having an android phone with android auto. And, of course, Teslas own system which is all inhouse.
There's little reason to use a phone in the traditional phone holders if you own one of those cars.
My dad, who's a fairly recently retired techy, is the only exception I know. I'm assuming it's based on perceived safety and less need to take his eyes off the road.
Granted, he took a long time getting a smart phone because they weren't allowed in his secured office, while dumb phones with no camera where allowed longer. On the other hand, he's also automated his home (a few times with updates), so it's really the one weird outlier.
The backup camera screen compliance was solved early on by just putting a 2-3 inch screen in the regular rear view mirror. There's no legal requirement to make it a big screen in the dash, that is 100% a design choice by the manufacturers unrelated to the backup camera.
I learned that very thing setting up my home automation. I was originally planning on designing and printing some sort of button arrangement. But I ended up buying a bunch of cheap Walmart tablets.
Easy to set up and keep updated. But... I'm not driving 70mph when I'm trying to dim the living room lights.
Volvo, the vehicle company that started out making bearings, used to make a big selling point in the 80's about their knobs, switches and buttons were good enough for people wearing gloves in the middle of the Scandinavian winters and intuitively placed for drivers to use without taking their eyes off the road. Saab were the same, but fast forward to today and the lunatics are calling the shots.
Even the flappy paddle gearboxes still have a weakness, namely they dont have a clutch peddle to dip when the traction control/esp decides to have a nightmare and ends up trying to cause accidents, where oil, ice or snow removes the grip and temporarily freewheeling is the fastest way to get the vehicle back under control before reengaging the drive system.
And these tablets like displays ruin the night vision, I actually liked the old Saab displays where you could press a button and it switched the lights off to loads of buttons and gauges for night driving.
Cars have got noticeably worse with these tablet displays.
I took advantage of the used car market to upgrade my 2021 Subaru to a 2024 (same car, better trim), there's actually MORE physical controls in the 2024 - hope isn't entirely lost!
In my experience in the USA, most fast food restaurants in the suburbs give away sauces for free, but the ones in cities charge for everything. Seems to also be correlated with whether or not the fast food restaurant has self serve soda fountains versus soda poured behind the counter.
In Poland I've experienced both ones that charge you per packet, and ones where asking for a packet will have the cashier grab a bunch of them without even counting, give them to you for free, and move on to handle another customer.
That applies only to ketchup packs, though - they always charge for sauces. The only place I ever got sauce containers by handful for free was in a KFC in Shenzhen, China.
Dealership margins, as I recall, are 10-20%, also not great.
Mfg margins have come up during the pandemic, interestingly, but historically have been very low[1]:
> While estimated aggregate industry operating profit margins are 6 to 7 percent (Exhibit 1), large variations in profitability exists across companies. For instance, some European niche, luxury companies make double-digit margins more akin to those of high-tech players, while mass-market (or value-focused) OEMs make 4 to 5 percent.
Their margins being thin is a matter of perspective. Most farms are running 1% profit margins on average and have massive variations in yield that auto production lacks.
Automotive grade controls are pretty expensive (it's not unreasonable to expect them to be operative from -40 to 140f, UV resistant, dust and vibration resistant, etc.), and as with all hardware, BOM cost is king. Even if the button can be stolen from an existing design, it still costs real money, and adds manufacturing labor costs.
The button then has to be tested, and kept in stock for service purposes. What if the button has silkscreen printing on it? It might be the same hardware button for the traction control and the trunk open button, but now they are different SKUs because the label is different.
So let's say I can eliminate 10 $1 buttons (that is an extraordinarily cheap button) by moving functionality to a touchscreen that is going to be in the car no matter what. I reduce the BOM cost by $10 per unit. That's a bunch of buttons that also aren't going to have warranty issues either. The wiring can all go straight to the head unit in a single bundle as well, and there are ten less connections for the assembly line to make. If I do that on a popular platform like the Corolla selling 750k units per year, I have just reduced expenses directly by 7.5 million, plus the cost of install, and simplified the supply chain.
I don't have the source but I read that in the process of designing a car there are different teams that design outer look, inner look, the actual functionality and at the time of designing interiors it isn't known where or how many buttons you need.
By having a huge touch-screen instead of knobs there is much less need to synchronize between the teams because the inheritor design team just needs to place the screen somewhere. And it's easy to imagine that it can significantly shorten the time to delivery and the costs.
Buttons are not just design, it’s more parts and assembly. On the high end it’s also a “less clean” look, unless you’re high enough for truly luxurious buttons and knobs’ designs and materials to be justifiable.
In every single car I've been in, the touchscreens are optional and you have some sort of knob you can use. This requires memorizing where things are in the software, however.
Slapping a tablet everywhere and letting the code monkeys figure it out is probably cheaper than making various knobs and buttons.
I dread the day I have to get a new car. Even Subaru, who are usually behind the curve, have gone all touch screen.
