(Far from it.)

Look up your local law.

First of all, it is hands free. Phoning here is legal, but hands free.

Here, it is legal to polish your nails while driving. It is legal do do your hair while driving. It is legal to eat while driving. It is legal to play with the radio in your car. It is legal to use Carman while driving. Its illegal to use a phone non-hands free though, and if the cops see a phone-like device in your hand they pull you over and check your caller history.

With a finger touch based device its very easy to change a setting. With a stylus in your hand it'd be quite more difficult to hit the right spot while driving, as well as shifting or reattach the steering wheel. No, I can't imagine someone using the stylus to pick a different track in any MP3 player. But in Canola as touch device I can imagine that works easily...
