Yeah I'm probably the closest to the knee jerk bicyclist advocate here lol

My standard view is usually it's always the motorists fault regardless of circumstances, but the cyclist had damn sure better be taking responsibility for his own life, as you can't be dependent on anyone else for it.

edit: eh, one of the above posters actually had a nice comment about speaking in absolute terms...so I'll temper it a bit. NEARLY in all circumstances I would blame the motorist. A motorist needs to be aware that not everyone on a bike, or even pedestrians, is an intelligent, rationally thinking human being, and needs to account for that in their driving, just as a cyclist needs to account for being invisible.

My threshold for assigning blame is pretty close to absolute in favor of the cyclist, but not completely absolute. It would stop just short of blatantly suicidal behavior, like alley cat races.

25mph, blowing lights through cross traffic, no brakes, yeah I don't think I would have a problem blaming a cyclist in that circumstance.
