after five years of riding I still have occasional FUC (failure to unclip) incidents like the one today where neither foot unclipped until I was in a cramp legged crouch headed straight for the ground, luckily I got one foot free and landed on one foot hopping forward into the cross traffic. The angels were watching out , there were no cross traffic cars and I pulled myself up and together without a total loss of dignity or major injury although I did whack the front of my upper leg aginst my handlebar (did I mention that I was in a flying monkey ninja super crouch and falling?) and now have a black and blue mark about the size of my hand- it doesn't hurt yet but is a bit swollen and will be colorful for a while.
