Granted I only have about 8 years of riding experience but my thinking is that if motorcycle is involved in an accident it is always motorcycle's fault.
Here is the logic.
On a bike if you crash you will get hurt and possibly die.
Therefore you should never put yourself in the situation to be in an crash, ever.
You always have more to lose than the car. I don't even want to go into "unforced errors" subject (going too fast, hitting a tree, etc)
Its one of those you always have to think two, even three steps ahead. I am hoping some of the older crowd will chime in (no offense).
Also on a bike you reaction instinct are almost always wrong. You must train yourself to think more and react less.
