I do not but...

I'm blind. So I don't drive and I don't own a smart phone. Can't afford one. I know some who can't even talk to their passengers and drive safely. Some people can't walk and chew gum at the sam4e time. I DO think texting isn't smart while driving, nor suefing the web. Both require one to take their eyes off the road. Otherwise I don't see it as any different that listening to a radio.
