I wish we could move toward pre-80's tactile controls. There certainly would be a lot more work creating limited interfaces that could work with them. It seems to me that it's less distracting when a function is a distinct control with some good feedback, like a switch or knob, than the controls that seem to line my dash these days.
It's probably not so much worth worrying about anymore. Automatic cruise control and braking are soon going to be the standard, and ease us into nearly automated driving. Computers don't get distracted.
