Just had this happen. I just moved offices at work, and my office is next to a guy I don't know. He's from Russia I think, works on a different team. We have window offices, so we both park outside our windows where we can see our cars, and end up parking next to each other. So I heard him leave, and looked out a few seconds later, and saw that his car door appeared to accidentally hit mine after he got into his car. He opened his door to the first stop, his foot hit his door as he was getting into his seat, and that sent the door out to the second stop, just barely hitting my door. You can see his door bounce off my car in the sentry footage. I didn't see any dents, chips, or scratches. But my car is pearl white, and does not really show chips because of the white primer underneath. Probably won't know until I do another detail. So what would you do? I'm certain it was an accident. He didn't even appear to give it a second thought. Probably does not even know whose car it is. But this guy will probably be parking next to me alot. I doubt he has any idea that I care about paint chips and dents, or that I have this on video.
