Turns out texting while driving is even more dangerous than we thought

In case you need and more proof that you shouldn't be texting while driving (or really, doing anything at all with your smartphone,) it's just been found that the practice is more dangerous than originally thought:

Drivers were asked to stop when they saw a flashing yellow light, and their reaction times were recorded, Yager said.

The typical time it took a driver who was not texting to respond to the flashing light was one to two seconds. But when the driver was texting, the reaction time extended to three to four seconds, and the texting motorist was 11 times more likely to miss the flashing light altogether.
Yager said the reaction time was the same whether the driver was typing a message or reading one.

One in five motorists admit to texting, emailing, and checking social networks while driving.
