I think a touchscreen is fine as long as real buttons exist for things a driver might want to manipulate while driving. My Outlander has a fairly large touchscreen that offers media and navigation control, but everything else (climate, drive modes, cruise control/drive assists, windows, locks, etc) is real buttons and dials, and there are also an extra set of basic media controls on physical buttons as well (volume, next/prev track, tuning).
I’m quite happy with that. And the passenger still gets all the touchscreen bells and whistles if they want to explore the map or set up playlists or whatever.
