Tracking teens driving

With GPS (global positioning system), that is. It tells parents how fast their kids are driving, notifying parents when a predetermined speed level is passed, the Associated Press reports. The idea is to get kids to carry a cell phone that contains a GPS chip that "sends out regular signals letting parents know where they are and how fast they're going." An alarm goes off in the kid's phone and a signal is sent to Mom or Dad when the family-set speed limit is reached. The organization behind it is "Teen Arrive Alive," and Gen. Tommy Franks just signed on as spokesman.
