Soon cops will be able to point a radar gun at your car and detect if text messages are being sent -- to try see if the driver is texting while driving.

On the bus this evening, I saw somebody texting while driving -- while moving, and I thought how stupid. He was obviously typing a message out on his iPhone -- not just hitting it once to read a message or for that matter dialing a number. And it was in traffic too. Maybe it's a good thing that law enforcement can see when a phone is sending out a text message while driving, without trying to look through the glass of people's cars.
