Many intersections could be safely altered to use yield signs in one direction, or converted completely to roundabouts. For some reason (and this is purely anecdotal), it seems that a lot of Americans, particularly older ones, seem to be very confused when first encountering a roundabout. I'm not sure why this is, but it may be a contributing factor to the prevalence of four way stops in the U.S. as compared to many European countries. Of course, in a world where everybody is free to do rolling stops at whatever speed they feel comfortable with, the real issue is that bicycles have a greater incentive to slow down at intersections compared to drivers since the costs of being wrong about one's ability to do a rolling stop are much greater for the cyclist. A cyclist should also be more aware of their surroundings since they are not sitting in a metal and glass box with the radio on.
