Speaking of things not supposed to be done while driving: We tested the Android car GPS thing this summer. The passenger is usually in charge of the GPS so the driver can concentrate on driving. But this darn thing says something like "touch input disabled while driving". So we still have to stop the car to do adjustments on the GPS. Very handy on the Autobahn, you can't just pull over and park... Who does things like this?

Sadly all other GPS navigators we used to use has gone downhill to the state of unusable so this is what we turned out using all vacation.
