Maybe my commute (car or bike) is different. But I rarely see cars blowing stop signs, by rarely like once or twice in the last 10 years. and even though we are in california... not so many "california stops" I have seen as more people run reds lights than stops signs. I do see more people doing a right on red without stopping.

and there are not just one or two stops signs either. One route (grocery store) has 2 4 way stops in less than a mile. the other route has a 4 way stop, a stop sign on a major road and the side streets to my commute street have stops.

So I just don't see this behavior. YMMV. Of course the last time someone tried to run a stopsign they almost nailed my car.
