This is one of the reasons that I'd like there to be a quick and easy way to report aggressive driving towards cyclists. Even if they can't actually do anything about it at the time, anyone who makes aggressive moves just waived any consideration that a future incident might be considered an "accident."
If you injure a cyclist, and have on record complaints against you for harassing cyclists, it should weigh heavily towards premeditated aggression causing injury.
