There's a huge difference between urban and rural riding. A four way intersection at the bottom of a hill with clear sightlines in a city is not something I encounter very often. I do see such places in the rural areas, and they come up in places where I may not even been passed by a car for the previous several miles. If I have clear sightlines in all four directions, there's no cars in sight, and I have momentum, why the hell am I going to stop? That said, if I have any inkling there's a car anywhere near the intersection, I'll stop.

I am, btw, getting really sick of this "drivers hate us because we roll stop signs" nonsense. I get the most hostility from drivers when I refuse to do dumb crap like riding to the right of a right turn lane. If I start second-guessing my safety decisions based on whether or not the drivers are going to like it, I suspect my safety margin will go way down.
