Touchscreens (or touch surfaces) should not be used for any kind of vehicle function. period.
If you need to take your eyes away from the road, it is a shit ui.
If you can't feel but have to look to see the result of your interaction, it is a shit design.
If you need to look at the center console and down, it is even worse.
There is only one reason to get rid of all the buttons and switches, and that is design. because "ape goes ohhhh!".
And that should not be a consideration that is prioritized over safety.
