As a bicyclist in San Francisco, if I follow the rules as written, I cause traffic. Cars expect me to blow through four-way stop-sign intersections, and if I stop and wait for the cars, the drivers get confused & don't want to go (afraid of hitting me, I suspect).
In terms of right of way, the rules as followed seem to be pedestrian > bike > car.
I sometimes give way to bicyclists at four-way stops because I can't be sure they didn't get there before I did and I didn't see them because they're small.
And of course, if a vehicle, be it a bicyclist or car, enters an intersection when I have right-of-way, it's not like I'm going to start crossing and intentionally run into them.
Where bicyclists really risk their lives if they start assuming cars will give way to them is when they blow through two-way stops, especially at night or at one of the many intersections with poor visibility.
