Comment on A San Francisco power outage left Waymo's self-driving cars stranded at intersections

  I admit I scratch my head at 4 way intersections with blinking yellows on all 4 though. Usually the bigger road gets the yellows for caution, the adjacent lanes have to yield.

    I’ve not seen an intersection with four blinking yellow lights in California; typically two ways are blinking yellow (caution) and the other two are blinking red (stop).

      Yeah the few times I’ve seen them set like that everyone is stopped, and just kinda waving people to go. I think it’s to do with power outage, and tye place I’ve seen it twice is a 4x3 lane intersection.

      I’ve seen both. Places where the lights are only intended to work at busy hours default to flashing red and flashing yellow. Lights with a power outage can be random but I’ve also seen flashing yellow in all directions. I don’t know why that’s even an allowed configuration though
