how can u compare talking over the phone and smoking they are two different things. When ur on the phone your mind is half on what the person is trying to say and u trying to reply back or dial a phone number thus taking ur eyes off the road at times. When your smoking ur either talking to  yourself ( u might be crazy but thats a different story) but any case your eyes are on the road.

I need to add this to the list of "benefits of smoking" You cant lose your concentration while smoking in the car lol.
