Problem #1 is that touchscreens are difficult to operate in applications where you're supposed to keep your eyes on the road.
Problem #2, which makes Problem #1 ten times worse, when when you get crap like Tesla does where the UI changes every month. They don't have any genuine functionality improvements to make, so they just move buttons around and hide or eliminate buttons "in preparation to make the car driverless". I never use Autopilot, much less Partial-Self-Driving. Give me back my UI from five years ago.
