I follow the BikeCammers subreddit. Based on what I've read, it seems that in a lot of jurisdictions, police have to actually witness the offense in order to issue a citation. But if the cyclist has video footage of the vehicle involved in the offense, and footage of the diver of the vehicle, then I don't see a reason a citation couldn't be issued if the cyclist was willing to testify as a witness/victim during the trial.
