Four-way stops are degenerate roundabouts.

I mean this in a geometric sense: you have traffic flows from different directions pointed at each other, and traffic proceeds in pulses through them. In SF you frequently see four-way stops where cars have all but given up on truly stopping.

I hold that any four-way stop in a city should be rehabilitated into a traffic vortex (roundabout or traffic circle) instead of trying to dealer-shuffle cars at each other through intersections.
