That's in agreement with the self-styled "experts" and I don't really know of any empirical evidence either way. But how many people drive a motor vehicle with a passenger, or passengers, and never speak to them or listen to them? I don't guess I see the difference between that and using the cell phone in a vehicle like I now have in which you touch one button on the steering wheel then everything is by voice; don't have to look at anything or do anything except talk and/or listen.
However, for me personally, it doesn't make a big difference because I don't use my cell phone in ANY way or anytime more than once every couple of months.:laughing: But I was taken by surprise and actually did receive a call on it while driving once this month, and I answered it . . . . . . wrong number!
