As Teslas and cars like it become more popular (especially in the EV space), more automakers will be adding touch screens. A lot of Fords new cars have them for instance. I was in a Hyundai rental a few months ago and it has a touch screen. I personally think it's a trend that will at some point be checked by the NHTSA or similar because they already know interacting with a phone slows reaction times, is distracting, and contributes to accidents. Why putting what is essentially a larger version of a smart phone on the dash should be better somehow is a question I've had since Tesla first started doing it.
