I drove a Prius where EVERYTHING was controlled a non-tactile touch panel. It was one of the most infuriating experiences with a car in my life and far more distracting.

In comparison my car has physical buttons and dials. If I want to adjust the temperature while driving I don't need to look away from the road, I just grab the dial and turn it a few clicks, same with sterio volume. I know approximately where the dials are so I can reach in the general area and know what I'm doing with out looking because there is something physical to grab.
