You frequently adjust your mirror when driving? That's something I do once in a few months (if that), twice if someone drives my car and adjusts the mirrors to fit them.. Perhaps you should adjust your seat instead?
Air conditioning? Yes. On longer drives, the positioning of the sun greatly determines whether or not my AC is running. Radio stations also are frequently changed, as is volume. If someone is talking to me in the passenger's seat, I instinctively turn down the volume of the radio for example.
I personally prefer physical buttons for these various tasks. Physical buttons are always there. I don't have to look at the screen to ensure that I'm on the "correct app" or whatever before trying to fiddle with the AC or volume.
