Accentuate the positive (ideas)

Some interesting ideas I've come across that I thought might be good for Boston and MA:

1) Drunk driving license plates: If someone is convicted of being a drunk driver the Registry will for a number of years make them register their car with license plates that indicate they are drunk drivers. Positives: public humiliation will hopefully be a deterrent, other drivers can be more aware of them. Negatives: The rich can set up trusts and corporations to get around this.

2) If a student drops out of high school they lose their license to drive. They can not receive a license unless they are in school, or have passed a GED.
