Discoverability is also an issue touch screens can help with - I enjoy that in the settings app on iPhone (I believe android is the same) one can search for a setting, rather than try to guess where a given setting has been placed.
But I don't want discoverability when my windshield suddenly fogs up and I can't see anything. I want to be able to just reach out and adjust the airflow without even thinking about it when I start noticing the fog in the first place.
Last time I had something useful was in my Volvo 740. After that it has been getting worse and worse. Even physical nobs can be bad, just round and smooth, without any physical notch that snows what direction it points.
Oh, I completely agree - everything important should be accessible and intuitive - typically that does mean a well-placed physical control.
But there are so many settings on a contemporary car that it would be impractical to have a switch for all of them, and even if they were, if it's something you'd like to change once in a blue-moon being able to search for that setting is really useful.
I don't know if this makes great sense as an example, but, say you're travelling from the UK to France (or USA to Mexico?) and want to have your speedometer show km/h rather than miles/hour. That's not a setting which should have a switch, but may be something useful.

Three presses in a Mercedes on its speedometer screen.
Many here argue there should be no screens in cars. The screen has some state you'll need to at least look at to get a bearing for where in the menu you'll need to navigate to. But most people aren't going to memorize the menu layouts for settings they rarely use, meaning they'll be looking at the screen when they interact with it.
The discussion is not about buttons for everything. Ofcourse I can't have a 737 cockpit from 1980 with buttons all over the place. Even planes get smart controls for the less used things. But the fan, the air direction and other very important and time sensitive controls HAVE to be physical in a car.
In regards to dealing with windows fogging, I prefer the system in my car that automatically detects conditions where it might fog and adjusts itself accordingly. On top of that the car has a physical max defog button close to the actual driver controls.
How is that better? Press press press press press press press press press press press press press press press cool just set one setting. Versus tap settings, flick scroll, tap to set.
One shouldn't be adjusting practically any of those things listed while driving. That makes having it as a physical control moot. And having physical buttons to navigate a selector on the screen is still a terrible thing to do when driving anyways.
My rule of thumb is if it's on the center console I shouldn't be messing with it when the car is in motion. If I'm supposed to mess with it while moving it's on the wheel or immediately around it.
And tbh between my car with a zillion buttons I shouldn't be pressing while driving and a small screen and the car where most of those functions I shouldn't mess with while driving are on the screen I prefer the screen. Far bigger screen to quickly glance at the maps when driving instead of a smaller one that's harder to see. Less space to actually see the media collection when I'm stopped and can safely navigate it.
That's not always the case, some things on the center console include skipping songs, flipping between audio sources, etc. If you need to switch to an emergency radio station from bluetooth, its drastically more complicated because there's no physical buttons anymore.
That's on the steering wheel on practically every car I've had for over 20 years of model years.
You probably shouldn't be flipping between audio sources while driving. But even then, I've had change audio source as an option on steering wheels before. Generally, you shouldn't be fiddling with the radio when the vehicle is moving, you should be driving. Keep your hands on the wheel and your eyes on the road, not on the stereo in the center console.
FWIW, in pretty much every car I've had since a 2012 model year I've been able to press a button on the wheel and say "tune to am 1510" and it'll tune that without having to take my hands or eyes off the wheel. Far preferrable than trying to look over at the radio to find the AM button again and figure out which knob is the tuning dial and then look to see I'm tuning to the right station.

Every time I try to talk to the voice assistant its the most horrible driving experience. It hijacks everything, and definitely sets me to where I have to pull over, or just stop trying to talk to it to get anything done. It does not understand me whatsoever.
