so i got some bike cops to pull over an aggressive driver on my way home just now. i waited for them, and then rode over to see what happened. i should have gone back right away because she gave them some sob story and since i totally neglected to tell them a few more details which would have shown her to be full of $hit no tickets were given. i talked with two of the cops for a while, and asked them some questions. when i asked about how they defined "stopping" the veteran one said that as long as a cyclist slows down and at least looks both ways at stop signs, he'd consider it stopping, but that it was open to individual interpretation. they were very approachable (and jealous of my nice bike) but still cops.
