"Please do not email, text, or even talk on a cell phone while driving."
I knew of a woman whose husband was killed while driving to work. In the opposite lane, on a narrow road, was a young woman who, while driving, was trying to put cream cheese onto her bagel, so she could enjoy eating it while driving. She unknowingly veered across the center line and the 2 cars collided, almost directly head on. The guy was killed. The woman was saved by the airbag in her car.
I agree that driving is dangerous. I agree that doing anything that distracts you, while you are driving, is dangerous to yourself and others around you. But I would not want to elevate texting and cell phones above other activities that drivers do -- eating is also a big risk, dropping food on your lap is distracting, etc.
The risk of emphasizing texting as uniquely dangerous is that drivers will start to underestimate the risks of other dangerous things they do.
