I've read here on the forum, not long ago, that for cycling, one should fall with the bike & deal w road rash rather than broken bones. like on your leg & shoulder, I guess. I forget actually. she had a broken knee cap some tears ago & so purposely avoided hitting that instead. recently using cleated pedals for the 1st or 3rd time I came to a stop & forgot I was clipped in. as I tried to remove my right foot I could see myself leaning (not yet falling) to my right, "leading with my knee" but I quickly uncleated & put my foot out. I was there thinking about how I would have fallen & thinking knee first, then a hand, but I really don't know. if I come across the thread about how cyclists should fall I'll share it. I think the responder was citing a pro racer talking about the same thing (how not to break an arm falling off a bike)

just found an article

"For spills from the side, use the back of your shoulder, hip and butt to absorb the impact instead of your arm as you hit the road. "
