This whole thing honestly reminds of the pushback against touch-screen only smartphones, along with the infamous "mixing the input and output on the same surface" quote (I cannot recall the exact quote, but my bastardized version provides a pretty good gist of it). People will scream, people will kick, but it will eventually happen.

sidenote: I was initially in the "bring the keyboards on smartphones back" camp as well, but given how well it all worked out 10 years later, I foresee the same happening with touchscreens in cars.
