My thought is that it would primarily be used for serious infractions such as a heavy vehicle user delibertly using their vehicle as a deadly weapon to attack a cyclist with. In which case you have a video footage record of the attack in question in progress which is hard for the cops to deny and do nothing about and useful in actually getting a conviction for the prosecution. I'm thinking ADW (fellony Assault with Deadly Weapon) charge or similar situation where having video footage of the attack in progress would be highly helpful especially if you end up needing to get restitution compensation for medical expenses out of the offending party.

I'm not running cameras yet so I don't know myself. I have had a few instances where I did get the cops involved and provided an eye witness account along with some physical evidence. Granted I haven't gotten what I wanted in most cases but in one case the offending parties were successfully charged with DUI and leaving the scene of an accident. Unfotionatly, it was my word against theirs (it was a party on wheels situation with a bunch of punks packed into a rig) that it was a deliberate attack so they weren't charged with anything there. If I had had a camera and footage that might have turned out differently (although back then most reasonably priced video cameras were very big and weighed about 20 pounds and took the big old school VHS tapes so it wouldn't have been very practical back then).
