My latest bike crash, on 28 August 2013, in which I broke my left collarbone (for the second time in 14 months), my back, and a rib was just like this cyclist's crash today in the Olympics. I hit my brakes hard to avoid striking a motor vehicle that was turning in front of me. (For what it's worth, I had the right of way.) This catapulted me forward, over the handlebars. I landed hard on my left shoulder and back. The only difference is that I didn't hit a curb. To this day, I cringe when I see a cyclist without a helmet.

Addendum: If you watch the video closely, you'll see that the cyclist's rear wheel was sliding to the left on the wet pavement. She probably panicked and hit the front brake hard (trying to slow the bike down), which threw her over the handlebars onto her head and shoulders. Been there, done that. By the way, 24 days after my accident, I did a 41-mile bike rally in Greenville (against doctor's orders). Have I mentioned that cycling is addictive?
