"Using a cell phone while driving - whether it's hand-held or hands-free delays a driver's reactions as much as having a blood alcohol concentration at the legal limit of .08 percent. (University of Utah)"
Quickly reading though that, it doesn't strike me as convincing.
People drinking to 0.08 drove slower, braked faster (!), had normal reaction times, and got in 0 accidents. Yet the study says they are more aggressive because they followed the car in front of them by 9.5 meters instead of 10.3.
This study doesn't make me think hands-free sets should be illegal, but that the blood alcohol limit level is too low.
