Waymo to update software after San Francisco power outage snarls self-driving vehicles

Alphabet unit Waymo said on Tuesday it will update software used to operate its self-driving vehicles and improve its emergency response protocols after its robotaxis stalled in parts of San Francisco on Saturday due ‌to a widespread ‌power outage that snarled traffic and gridlocked parts of the city.

Waymo paused service Saturday evening following a fire at ‌a PG&E substation that knocked out power to roughly one-third of the city, affecting about 130,000 residents and forcing some businesses to close temporarily.
