Earlier quoted context omitted.
What exact type of input is being grabbed by these screens? "Critical pilot systems"? Touchscreens already exist in airliners, for systems used by crew and passengers, but that's beside the point.
Critical driver systems (i.e. steering, signaling, acceleration and brakes) aren't controlled by touchscreen in any car I know of either, so if non-critical systems are beside the point, what is the criticism here? Or are you thinking of some particularly extreme cars that are even more reliant on touchscreen than the Model 3?
I also imagine that there are other reasons for both airliners and cars to replace buttons with touchscreens, namely that of cost instead of prioritizing safety and stability, and in general I am not a fan of that trade-off. But I'm also not claiming to be representative of the automobile market in general.
