Ford is adding a MyKey system to their 2010 cars. It’s a separate key that is assigned to your car specifically for your teenage driver(s).

The key limits the car’s top speed to 80 mph (although I don’t know why any teenager needs to be driving that fast.)

The key limits audio volume to 44% of the stereo’s ability.

The key gives a more persistent seatbelt warning (it beeps obnoxiously until a seatbelt is put on).

The key also chimes at 45, 55, & 65 mph.

Personally, I think this is a great idea for teenage drivers. It would also be nice if it was able to somehow block cell phone use while driving. I just wish it wasn’t an optional package for new car buyers. I think this should be standard on all cars. I also think OnStar should be a standard safety feature but I doubt that will happen.
