I think tactile controls should be those things you would want to change while driving:
* Climate control heating/ac/defroster temp up/down fans higher/lower
* windows up/down
* signal left/right
* windshield wipers
* volume up/down
* audio basics (next track/previous track)
This allows you to keep your eyes on the road and rely on muscle memory to make the changes quickly. It's an important aspect of auto safety. Things like gps route selection, loading music into vehicle or configuring playlists can be done with touchscreens as these are complex tasks that are unlikely to be done while driving.
