Well, in my god only knows how many years of biking on the road, today was the first time I made physical contact with a vehicle. It was the third time I've been in an altercation that drew blood (not counting getting skint up as a small kid). The first I went down in a peloton pileup, and the second time I was in a curb vs. truck grill situation. Both my previous incidents occurred when I was in my early 20's now I'm 40, so about once every ten years I screw up.

I've had something thrown at me once, and had to stand my ground, when a drunkard got out of his car to yell at the bicycle, once. I've had folks honk and yell out the window as they pass about every other day, you just blow those off.
