Waymo explains Saturday’s self-driving shutdown in San Francisco.
When a substation fire cut off electricity across the city, Waymo SUVs stuck at malfunctioning stoplights quickly became another headache, and now the company is explaining it as an issue of too many remote operator assistance requests:
While the Waymo Driver is designed to handle dark traffic signals as four-way stops, it may occasionally request a confirmation check to ensure it makes the safest choice. While we successfully traversed more than 7,000 dark signals on Saturday, the outage created a concentrated spike in these requests. This created a backlog that, in some cases, led to response delays contributing to congestion on already-overwhelmed streets.
