While I agree you can't account for everything, I do think some people overlook their own bad decisions and place the blame elsewhere.

It's a small sample size so it does have some limitations, but interesting either way.
Speeding was mentioned above. Someone pulls out in front, did they miss the motorcyclist or did they not look far enough given the speed (could they look far enough?)? I remember reading about an accident in the past year or two that was initially reported as "car turned in front of motorcycle" but then later excessive speed of the motorcycle was reported. I know this isn't always the case, but I think too often people are quick to place blame anywhere else.
I saw a video on facebook in the past couple of days of a motorcycle hitting a mattress (

I'm not going to say I've never broken traffic laws or ridden aggressively etc, but I've seen other motorcyclists do stuff that just makes me cringe. Driving down 6th in my car and getting 'strafed' by bikes, frankly videos of people dragging knees in canyons, etc. Can you avoid every accident, probably not. Can you greatly reduce the chances, absolutely.
