i was sprinting through and intersetion about a week ago, and half of my aluminum handlebars snapped off in my hand. i went straight down but it didnt hurt as much as it could have. i got alot of funny looks riding with half a handlebar. later i figured out that cable holes drilled by someone other than me weakened the bars. it is a really bad feeling to be pulling on the bars real hard to sprint and have them break off.
ive had some really near misses lately. like people opening car doors, or delivery trucks parked and nobody letting me out of the bike lane when im going 25 or faster.

i've done the zero mph clipless thing a bunch of times. "oh **** im falling over and theres nothing i can do about it"

and last but not least ive fallen a few times track standing while clipped in.

while touring, after using a computer (and being inside a building) for the first time in a few weeks i smacked straight into someones back wheel and went down. and we also had a nasty dog related pileup in the rain.
