Cites Minority Report as the reason for all of this.
If you only remember two things about CES this year, make those two things laser headlights and gesture controls. We have here a video of Dr. Verena Reischl, who holds some unidentified position at BMW (we're guessing it has to do with engineering), giving a demonstration of how gesture controls will be integrated into future iDrive systems. The cabin mockup isn't quite as complete as VW's gesture control concept, but it makes the same point.
We can't say for sure when this sort of thing will become the norm, but we can probably look forward to lots more touchscreens first.
