Wow!! good job your not a Judge
Its a huge problem but not a new one is it really? I like the law brandon05 mentioned about anyone under 18 yrs old cannot have more that two other kids under 18 in the car with them without an adult.
This needs to be implemented as it certainly encourages this kind of activity.
You know my thoughts on this would be a car that could be modified so that its max speed would only reach 40 mph and anyone under 18 would HAVE to drive this type of car with what would be known as a 'learner key'. It would be illegal for insurance companies to provide insurance for an modified car for an under 18. Once they were 18 they would be re tested and given the 'FULL KEY' to modify their car back to standard speeds. Yes i know these things can be tampered with but anyone caught would have a 5 yr driving ban.
Sounds difficult but when you consider its already done with Jet Ski's with learner keys surely it cant be that hard to implement.
