Don't Text and Drive!

According to a Virginia Tech Transportation Institute study, texting while driving is 23 times more dangerous than driving while not distracted. By comparison, drunk driving is "only" seven times riskier. Unsurprisingly, the study's authors encourage regulators to ban texting while driving:

Texting should be banned in moving vehicles for all drivers.

I couldn't agree more (though I have been guilty on occasion). Talk about a massive negative externality!
