Take this story with a grain of salt but it’s useful to keep complexities in mind when regulating:
The Insurance Institute for Highway Safety says that 3 of every 4 states that have enacted a ban on texting while driving have seen crashes actually go up rather than down.
It’s hard to pin down exactly why this is the case, but experts believe it is a result of people trying to avoid getting caught in states with stiff penalties. Folks trying to keep their phones out of view will often hold the phone much lower, below the wheel perhaps, in order to keep it out of view. That means the driver’s eyes are looking down and away from the road.
Very appropriate hat tip: Offsetting Behavior.
