In fact, it's somewhat telling that most bicycle fatalities don't involve a cyclist doing something stupid: most cyclist law-breaking is done when the cyclist believes it's safe to do so, and they're usually very attentive and aware of their surroundings for the duration. It's when the cyclist is in a normal state, and has no reason to expect a surprise attack-by-car, that the fatalities happen.

(As a pedestrian, I very much sympathize with this. I tend to jaywalk quite often when walking, and when I do, I'm super attentive and ensure it's safe before crossing. It's probably more likely that I'd get hit by a car when I have the right of way than when jaywalking. But I'm still breaking the law, as is the cyclist when he/she runs a stop sign.)
