I voted YES only because it would be VERY little improvement over hands on. I feel anything whethere it is in your hand or not is a mental distraction. I see way to many people all over the road with a cell phone, KUDOS to those of you who use a cell while driving and still drive good. Me myself and I do not drive good while onthe phone so I do not do that myself, and I also thank God for giving me the ability to know that I am not good at doing that.
