I don't think I'd waste my LEO's time with camera footage unless it was really egregious. I'm not saving, or posting, every guy who makes a traffic error. I'm after two things:

1. If someone hurts me, there is a a significant confrontation, etc.
2. In the event of an incident, I want video footage.

While I wouldn't waste the time of law enforcement with something minor, or accidental, I would call a cab company with a cab's license if they behaved poorly (or a truck, bus, etc.).
