re: #200 WindUpBird

Harvard researchers estimate about one in 20 U.S. traffic accidents involve a driver talking on a cell phone, but say laws banning cellular phone use while driving would cost society about as much as it would save.

“We calculate that around 2,600 people die each year as a result of this use of the technology,” said researcher Joshua Cohen of the Harvard Center for Risk Analysis. Another 330,000 are believed injured.

Cell phone impairment is clearly much higher than marijuana impairment, which has yet to be established.
