I think if I was a kid with that I'd put the car up on jack stands at a friends house and take the tires off and get it going about 140mph. Then bolt the wheels back on, go find some empty parking lot and drive in circles each direction for a while to set the hard cornering warning off. After doing all that I'd be ready to go to the drag races where I can speed legally and do some WOT accelerations to get the acceleration warning to go off. Do this for about 3 weeks and I'm sure you're parents will realize that this device is a piece of crap.

As stated above, teach your kids how to drive and be responsible. Send them to a driving school or go autox with them to teach them limits of the car. If you teach them to be responsible, to be courteous, and to drive safely you won't have to worry about your kids. It's the other drivers on the road you need to be worried about.
