What about dual fault?
The only serious automobile accident I've ever been in (as a 16 yr old), I was turning left across two lanes of stopped traffic, after being waved on by both drivers. A third driver coming down the emergency shoulder hit me at 50mph. Destroyed both of our cars. The policeman called it dual-fault, since I "failed to yield to oncoming traffic". Even though he was in the lane illegally (and speeding), he was "oncoming" which I didn't yield too.
I wonder if the same would have been said at that moment if it was a cyclist.
