Since Fiery seems to have struggled to understand the nuance of the point I made, I'll re-state it.

Technique may help, and it's perfectly fine to practice it if you like. I'm only saying the benefits of said technique are overblown. I usually tend to land pretty well and have come off lightly in most crashes. I've also broken my collarbone twice, once quite severely. I went over the bars descending on my cross bike. I tucked. I rolled. My clavicle broke like a dry twig. I did it "right," yet I suffered the worst injury I've ever had in my life. The point isn't that this stuff is useless. The point is it can only do so much, and not very much at that if things don't go your way.

There are a lot of variables in any crash. The fact is, the combination of speed, height off the ground and mass mean you have a lot of kinetic energy that needs to go somewhere. You can try to redirect it, and that can help, but it very often isn't enough and often for reasons that aren't in your control. That's what this really is about: the illusion of control. Once a crash has started, many of you wish to believe that much or most of what's going to happen next is still under your control. You're wrong, but I suppose it's harmless enough to believe it. But it's still a delusion.
