I crashed on a downhill doing 42 mph according to the max speed on the speedo. Besides a ton of road rash, I had a concussion that caused temporary blindness in the left eye.

FWIW, the crash was caused by the front part of a Look cleat snapping off followed by my foot coming off of the pedal. Slipped down on the top tube, high speed wobble ensued and the rest was wham, bang, that's all folks.
