I definitely don't recommend this and I regret taking the unnecessary risk, but I understand what Soggy was talking about:

Last summer I was riding home from work when jacktool in a little p.o.s. pickup starts to ride my wheel, honking, yelling obscenities, you know the scene. When he told me to get off the road and onto the sidewalk, I asked him to pull over to the curb so that we could discuss the California Vehicle Code.

Instead, he swerved at me and took off. That made me really angry so I put it in the big ring and chased him. He was now stopped at a red light and as I closed to within 100m, I could see him see me in the rearview mirror.

"Hey! I want to talk to you! Pull over to the side of the road!"

Jacktool pickup driver must have been frightened by the sight of little ol' me, wearing a button-down shirt, tie, and khakis, bearing down on him and screaming at him to pull over. So he jumps the light and roars ahead.

Only to have to stop at the next light a few blocks up. Where I catch up to him again. This time, I pulled up to the driver's side window and said again: "Hey, pull over to the side of the road. I want to talk to you about traffic law."

The light changed again and I can see him making a couple of evasive maneuvers, going right and then left. I'm still hot so I cut across a parking lot and nearly caught him at another intersection. He blew the sign and hopped onto to a freeway on-ramp.

What a tough guy. He's all big and bad with his finger on the horn and his foot on the gas pedal. Here I am, just a state worker on a bike.
