The problem with using touch in a car is that you’re supposed to look at the road, not at a screen. Whether something is easily controllable could be a matter of life and death. Something physical you can reach by muscle memory is safer in this context. So yeah the basic controls should be tactile and intuitive. Anyones grandma should be able to figure out how to turn on the wipers if the rain sensor didn’t do its job. Or adjust the fan quickly if the window fogs up.
