If the police will not do anything, sit down, and relax for a few minutes and consider yourself lucky that you were not in an accident. Then you would have problems. He probably didn't have insurance anyway and you would really be mad then.
Trying to find the guy will get nothing acomplished except more problems. He could come back at you with a law suit because you could not prove it was him. It is your word against his. I know it is hard to do, but I think it would be better to just drop it. I hope this helped.
