Mild Ride

Parental controls for cars--when my kids were born 14 years ago, I figured something like this would be available by the time they started driving (probably still too late for us, since will only be in new cars, and I don't see one of those in the immediate future...)

MyKey allows parents to limit teenage drivers to a top speed of 80 miles per hour, cap the volume on the car stereo, demand seat belt use and encourage other safe-driving habits.

also highlighted MyKey’s low-fuel warning, which lights up earlier than normal. He called it “a little thing for Mom and Dad.”

This is a great idea. I think 60 mph would be a good upper limit. Maybe 50, if you could be sure your child wasn't going to need to go on the highway.
