      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.

      I mean.. good question but that won’t really sway my view that roundabouts are a far better design choice. Also just selecting tweets from my mentions here but this seems doable within reason:https://mobile.twitter.com/sigfpe/status/973022455378755584 …

      In the UK they just paint a white circle in the middle of an intersection and like magic it's a roundabout and the traffic can keep moving.

          I live in Massachusetts. Only a physical barrier will work. Mass. drivers cross solid lines all the time and never yield.

          It probably does work better in Washington State: drivers are aggressively polite there.

          Heck, half of Seattle has neither stop signs nor roundabouts. You just slow down, check for traffic, then come to a grinding halt whilst *insisting* that the other person go first. No, you go. No, really, you go. It's okay, you go. No, no, please, you go first...
