...back in the good old days when no one got run over in crosswalks because we had no cell phones.
Cause and effect. If we say cell phones, or more accurately, the distractions brought about by using them while driving, are the cause, the CAUSE of accidents, then we must compare that danger to those of using the radio, smoking and drinking and eating in the car, putting on makeup, reading the paper and having sex while behind the wheel or we're not addressing safety; we're addressing pet peeves which is no way to make law.
I almost pulled out in front of a car the other day while talking to one of my kids. Ban it? How many accidents are there because people are daydreaming? How many accidents are prevented because people have routines such as smoking, radio, drinking coffee, that actually help them relax and concentrate better on driving?
