In Portland, OR we have 4-way intersections where the stop signs alternate every 2 blocks. Drivers still tend to stop at every intersection, even when they have no stop sign.
Ha, I don't come to a complete stop, but I'm guilty of slowing down at the intersections without stop signs because I've experienced enough instances of cross traffic blowing through their stop signs. In the city I think it would probably be better if all intersections were four-ways.
