I don't think that's the case. e.g. My car's AC controls are physical. I sometimes look at the dials but that's a passing instinct rather than a need. There are three dials and I can feel for the one I want to press with my left hand (our drivers seats are on the right) and then turn it. If I'm adjusting the fan, the sound from the AC gives me sufficient feedback to know if I've set it correctly. This is especially apparent when I'm paying attention to the road more than usual (e.g. while driving through an unfamiliar area). With the entertainment system, it's a tree of menus on a touchscreen to find what I need to do and then the screen has several buttons neatly arranged which I need to look at (not just feel for) to find what I need. When I tap on something, it's not immediately clear to me without looking and verifying whether the function has been executed or not.
