When speaking with someone in a moving vehicle, you automatically adjust your cadence. In difficult driving situations you both will concentrate more on the road, talk less, making an accident less likely. When you are talking on your cell phone neither of you have any idea about the others situation.
Hear, hear!
Wrong, they can't. And they don't. Anyone can make baseless statements. ;)
