The serious crashes I have had offered ZERO time to respond. So even if I had the reflexes of a cat (and I surely don't), I'm not so sure a crash strategy would have helped.
BTW: There is evidence that the reason we have collarbones is to absorb some of the impact from falls that would otherwise be absorbed by our ribs, neck, and skull. Collarbones generally heal well, and by themselves.
