Truth be told, this was one of those slow motion wrecks, and I would've had plenty of time to unclip, but I rode the bike all the way down with my foot on the pedal (working the brakes to slow down as much as possible before impact), and the pedal actually shielded me from the pavement as I slid. If I'd tried to bail, I don't think I'd have been able to get my feet under me the way I was leaning over.
