Mr. Silver's got it....but don't expect the driver to get a ticket. If the cop issues a warning, consider it a moral victory. But report it if you can.

Locally we have a guy that rides with cameras attached to his bike ( http://bikesafer.blogspot.com ). When he is buzzed by a vehicle, he takes the tape to the appropriate authorities. He has successfully gotten tickets issued and he has educated at least one trucking company, but he has also shown us the ignorance and anti-bike stance of the local system and their lawyers. Currently, all he asks for is a warning. He's getting the warnings issued. Baby steps.
