That sucks, and I'm very sorry you got hurt. It was not your fault by any reasonable estimate. HOWEVER: I've learned after several crashes of my own, that even when it's not my fault -- when I've done what you're supposed to do to the letter -- I still could have somehow avoided the crash. The same is true here.
It's an unfair burden to the cyclist, but in addition to looking out for ourselves, we have to be responsible for the idiots who aren't.
It's very little solace to be in the right and in the hospital.
Heal up.
