I would love a hybrid approach: gimme touchscreens, gimme some physical controls especially for hardware actions like popping the trunk. C'mon, a software update isn't going to delete my trunk, so put a button for it.
I'm with you on this, but it's a pretty great example of when a touchscreen isn't a safety hazard: very unlikely I'll want to pop the trunk while I need to keep my eyes on the road.
(you know, it could be because touch sensors don't work with space gloves)
