My brother showed me a video he got from the Salem bus company after a car moved into his lane and he over-corrected to get out of the way. The bike tipped over long enough to dump him and break his arm, then bounced back upright and followed the offending car for quite a ways. The bus didn't actually record the wreck, but the car and the empty bike (named Christine) come up on the bus. It's weird, and I asked him to post it on Youtube but I don't think he has.
The detail wasn't good enough to read the car's license plate so it was never identified. No contact so it wasn't even a hit and run.
