I thought of this a long time ago

I think we should be able to do it as parents to our childrens vehicles. To all city, county, state and/or municipal vehicles too. 

There is no reason that people should be allowed to speed given the chance that are being provided a vehicle for work. Take the chance away from them and we save gas, lives, ozone and even maintenance costs.

Personally I would like to take the radio out of my daughters car for the first 6 months she is driving.   But I would be extactic if automakers gave me this option.
