Don't Tell My Dad

But Ford is coming out with a car next year that allows parents to pre-set how fast the car can go when being driven. No, really.

From the article:

In addition to speed limits, MyKey also will limit the volume of the audio system, and it will sound a six-second chime every minute if seat belts are not fastened. The chime sounds for adult drivers, too, but ends after five minutes to avoid annoying adults who adamantly don't want to wear seat belts, Buczkowski said.
Parents also have the option of having the car sound a chime if the teen exceeds 45, 55 or 65 mph.

Actually it should probably be my mom who should be more concerned.
