Yeah - I do wonder if a giant touchscreen with permanent controls (Zero context switching) could be nearly as effective as a climate panel with fixed buttons. Part of the issue of a touchscreen in a car today is that every single view is context dependent, whereas a physical volume knob is always in the same spot, performing the same singular function.

My chevy has fixed buttons/knobs, but the only one I don't have to look for is the volume knob. There are too many climate buttons that I use maybe once every two weeks for me to gain any muscle memory from pressing them.
