As I’ve said elsewhere, touchscreens are fine in cars for functionality that isn’t something cars already had.
I don’t need a dedicated button for the Now Playing screen on my podcast app. Or for Points of Interest in my Maps app. But I would still like to use those things in my car the way I have become accustomed to.
But I do want physical buttons for everything I’ve always had physical buttons for.
My current car (a 2022 Ford Escape PHEV) has actual buttons and dials for climate control, media controls, etc. Everything you want to be able to do without looking. But it also has a nice touchscreen to support Apple Car Play/Android Auto.
This is the proper balance, I think. Let the car continue to function as a car without the touchscreen, but the touchscreen should be available for the luxury elements a car can provide.
