Good job on getting his license plate, keeping your cool, and talking to the cops.
+1 on getting him on record for a complaint. Will likely go nowhere this time, but as others have mentioned will add credibility to future complaints against him, and protect you in the future.
-1 on the Buddha comments. Too f#$(in' bad if he had a rotten day. It's assault with a deadly weapon. It's no different from a person swinging a bat or a knife at you. A car will only "always win" so long as people don't stand up for what they think is right.
A helmet cam would be a good idea in either case.
