I've only had one experience of a real jerk motorist, and this was someone who lives in my neighborhood who attacked me in our neighborhood! Her Maryland license plate is "HAYAAH" and she drives a BMW sportscar. That gives you an idea of the type...

Coming up to a green traffic light, I had taken posession of my lane in good time. She comes up behind me, blaring the horn. I move out further into the road to prevent her buzzing me in the intersection (with oncoming traffic waiting to turn). I move to the right once clear of the intersection and she buzzes me on the next stretch and overtakes before very quickly decelerating at the next (red) light. I pull up beside her and ask her why she was more concerned about making the light than splattering my head over the road...and now she's just sitting at a light while I can ride ahead of her! She started ranting, so I rode on. Clearly she wasn't intelligent enough to have a rational discussion.

Now I just let my dog crap in her yard and don't pick it up. I have fantasies of going at her pretentious little b*tch-mobile with my bike lock, or smearing dogs**t all over her house/car.

On another note, please stop calling them cagers. It doesn't help the cyclist/motorist relationship, and I'm sure many of you are also motorists.
