Which, in a single lane scenario, have the additional benefit of decreasing collisions and injuries for pretty much all involved. They are also successfully proven in a roadway network (the proposed scheme here doesn't consider that case). Roundabouts are a great analog tech. Roundabouts get less compelling when they are multi-lane (can start to suck for pedestrians and bikes in particular). They can also take up lots of space. But, on the whole, roundabouts be good.
