Another time I looked behind me on the bay bridge coming out of SF going to berkeley, and when I turned around the dude in front had slammed on his brakes.
I grabbed the front brake, and was almost up on my front wheel but smacked into his bumper anyhow, which tossed me up onto the handlebars and racked my nuts.
So here I am laying over the handlebars with my nuts aching trying lamely to scramble down off the bars and the bike is held up by just the contact with the bumper.
The bike slowly falls over with me on top of it and I go crash, falling onto the ground with the bike laying on my leg in a way that was pinning me down.
Bunch of people hop out of cars, people are going "DONT TOUCH HIS HELMET!" and whatnot and i keep asking them politely to please pick the fucking bike up so I can get my leg out.
Finally someone does, and I get up and brush off and get back on my bike, thank the dude who picked it up, and assure everyone I am ok.
Everyone gets back into their cars, and I'm sitting there waiting for traffic to move. I notice my left mirror is jacked up and go to adjust it, and it snaps off at the base nut.
I'm standing there annoyed with the mirror in hand, and I turn and chuck it off the bay bridge, with every eye in every car on me.
