I agree with you almost 100%. But I do think there are the occasional accidents where it really can't reasonably be avoided (Deer out of the woods, for example). But those instances are far fewer than people acknowledge. I've always felt that 99% of all accidents happened because two parties weren't paying enough attention. Sure, one party may be totally legally responsible, but that's not to say the other party couldn't have avoided it with reasonable diligence.
And on a motorcycle, that can be a matter of life and death. I think a lot of people don't take accidents where the other party was "at fault" as learning experiences.
