Touchscreens were never popular with customers. Manufacturers kept cramming touchscreens in cars and using them to control everything becuase they were being stupid with new tech.

Edit: I guess I should have been clearer. I was talking about as a replacement for tactile controlls in a car like the article is talking about. Reverse cameras and other things that are good to have a touch screen for make perfect sense but using your touch screen to control your Air conditioning in a way that you have to divert your attention from the road to operate sliders and buttons on a touch screen is dumb as hell.
