Bumped the car in front; guy was furious. We pull over; inspect the car. His bumper is in pristine condition...aside from his car being a cheap old car & it having bumper stickers. Took about a dozen pictures. No damage occurred on my car (a higher end car) or his. No police report; no insurance information was exchanged. Can he come after me in the future say if he wants a new bumper, which the pictures clearly show his bumper & mine are both in excellent condition. We exchanged phone numbers, and he left messages saying the quote on fixing his bumper is 800 plus! Insane; I have the pictures to prove nothing was wrong. I think he saw my car; valued it up, wants a new free bumper?? He's contacted his insurance & made a police report?? What now? occurred in CA.
