That is really scary.
I do ride really defensively on the roads - I mean, bike vs. car is a no-brainer. Though I will admit that I occasionally succumb to road rage while driving (not that I drive like a mad woman but I do, um, honk and give other drivers the finger if I feel that they deserve it), I would never dare to show any sign of aggression towards any car. I have been honked at more times than I can recount (as most of you have I'm sure), but I just ignore them. Most of the time there is nothing I can do about it - ie, I have no room to move over. Once they honk at me, they've all just gotten around me. I think most honk at me if they feel I've taken the lane as opposed to riding very close to the curb, which I don't like doing b/c I feel it's dangerous (to me).
At any rate, I am glad that this cyclist did not get hurt.
Trying to be the person my dogs think I am.
