Footage posted by TikTok user @brahmsstan and obtained by Storyful shows several Waymo vehicles stalled at an intersection in the Mission District neighborhood.
While the Waymo Driver is designed to treat non-functional signals as four-way stops, the sheer scale of the outage led to instances where vehicles remained stationary longer than usual to confirm the state of the affected intersections. This contributed to traffic friction during the height of the congestion.
I dunno man. Even a single traffic signal going out will cause a backup in that intersection even with no self-driving cars, because a 4-way stopsign follows round-robin rules, and the throughput of that is simply much less than a timed traffic signal (which is why they were invented).
I'm not saying Waymo did as well as human drivers would have, but it's kind of hard to tell. Nothing obviously bad happened like the cars losing communications with HQ and going crazy or bricking in the roadway.
