ABC News: Newest Key to Teenage Freedom

Ford Motor Co. announced today it will offer a new feature, starting next summer on some of its 2010 cars and trucks, that allows parents to set safety limits on teen drivers through a high-tech car key.

Watch "World News With Charles Gibson" tonight at 6:30 p.m. ET for the full report.

Want to ensure your teen can't drive over 80 mph? Or listen to loud music while driving? Or cruise around town without buckling up? A computer chip in the key allows parents to add those features when the key is in the ignition, and ensures a six-second chime will sound every minute if teens don't fasten their seatbelts. Drivers will also be alerted earlier than usual if they're low on fuel, with the computer chip triggering a warning at 75 miles before the gas tank is empty.
