I could type on my old Nokias etc without ever looking at the message. It was flawless. If one wanted to do it whilst driving (not that anyone ever would, of course) it could be done without ever looking away from the road. That's the power of actual physical feedback. I'm sure there's someone somewhere who can prove me wrong and touch-type flawlessly on their touch screen phone. But in most cases you're relying heavily on auto-correct to make a parseable sentence. Which means you'll need to look at the screen a lot. The radio/Cassette player in my car is all buttons. I can change stations, volume, switch to tape etc without looking much at all. Some buttons I might no remember their place - but here's the crucial thing. I don't have to keep looking until I make contact. I glance, see where the button is, and then feel for it. A touch screen simply doesn't give you that, you either need to see yourself making contact or wait for the software to do something you may (or may not) have wanted. If it's wrong, you're now trying to fix that and try again. I do not believe that touch screens reduce risk in interacting with car functionality, indeed I'm pretty sure they increase it.
