It was an accident! Unlike cars, bikes are quiet. I still think the kid can learn a lesson without everyone involved being nasty. I believe that if you get nasty, threaten legal action and the like, the kid will learn the wrong lesson. The lesson should be to pay attention, take responsibility for your actions and resolve problems in a responsible manner. He may end up learning how to lie his way out of getting in trouble with his parents and the law, and continue to be a biking menace. A little personality goes a long way. People can make mistakes and learn from them. It often happens that good can come out of a bad situation...for all involved.
