If you intelligently disable in-car functionality (such as GPS when the car is moving), people will reach for another device to get that functionality. It's naive to think that constraints will automatically change users' desires.

I believe Apple is sending out the wrong signal about driving+other activities at the same time.

Sure, people have already picked up bad habits, but that makes it ok to encourage that behavior if they are going to do it anyway?

Maybe Apple does make certain activities less dangerous, but it's still making access to distractions easier and I think that's a bad thing.
