I do not understand why getting passed by a bike makes certain drivers FREAK THE **** OUT.
A couple days ago, I passed between two cars at the end of a red light. I got pretty far out in front of them and moved to the center of the right lane (it was a 3 lane downtown street with parallel parking on both sides). I hear this engine come screaming up behind me, and this guy starts riding my ass HARD. I turned my head to see that it was a really nice, newer VW Passat and the driver was a pretty old guy, so I just took my chances with him and stopped, got off my bike, and stood there in the middle of the road (there were no cars behind him). He accused me of going too fast, and I fired back that no matter how I was riding, he's got no excuse to threaten my life with his car (there was a lot more profanity involved than that, though).
The best part is that this guy had a bike rack on his car and was wearing a cycling jacket. He looked a couple times like he was going to come after me, but eventually he just stopped yelling and got back in his car and sat there in the middle of the road for a while before leaving.
Seriously, what do you guys do with this type of thing? It's happened to me at places in the road where I just had to ignore the person until they turned off because there was no shoulder and no way for me to turn onto a side street. The bottom line is, I don't want to get run over because some moron accidentally nudges me with his bumper while trying to intimidate me. Maybe I could fill a fog machine with bear mace and carry it on a trailer behind me?
