The worst I've ever been injured in a bike crash was riding down a dark street at night with no lights... I couldn't see where the ground was to land properly... every other time I've been able to roll with the fall and not suffered serious injuries (Including getting hit nearly head on by a truck)
Alas someone has been watching too many martial arts movies, you're still dealing in the realms of physics, if you get clipped and go over your bars, or hit hard enough to get a little bit of air on you, there is only so much you can do, and everything you do is going to twist the rest of your body (being as you have no force to act upon). I agree there IS a way to fall to help prevent injuries, but it isn't a guarantee, it's a complete gamble.
You can try, but most of the time you're not going to be able to judo-roll your way out of every encounter.
