Waymo resumes service in San Francisco after robotaxis stall during blackout
Waymo resumed its San Francisco robotaxi service after a citywide blackout left many of its vehicles stalled on streets and at intersections.
What happened
A massive power outage on Saturday knocked out traffic signals and transit systems across San Francisco. Social media showed multiple Waymo robotaxis stalled while human drivers navigated around them.
Timeline
- Saturday evening: Blackout hits — traffic lights and Muni service disrupted; Waymo suspends service in the city.
- Late Sunday afternoon: Waymo confirms it is resuming service, per a company spokesperson quoted by TechCrunch.
- Cause: Reports indicate a fire at a PG&E substation affected roughly 120,000 customers, with tens of thousands still offline into Sunday.
Waymo's response and technology behavior
Waymo said its self-driving system treats non-functioning traffic lights as four-way stops, but the scale of the outage caused some vehicles to remain stationary longer than usual while assessing intersections. The company added most active trips completed successfully.
"We are focused on rapidly integrating the lessons learned from this event, and are committed to earning and maintaining the trust of the communities we serve every day." — Waymo spokesperson
Key points
- Waymo suspended service temporarily during the blackout to prioritize safety and system assessment.
- Traffic-signal failures and gridlock complicated robotaxi decision-making at scale.
- Company emphasizes rapid integration of lessons learned and trust-building with communities.
Impact on San Francisco
The blackout disrupted traffic signals citywide and affected Muni mass transit. Mayor Daniel Lurie urged residents to avoid driving unless necessary.
| Metric | Detail |
|---|---|
| Customers affected | About 120,000 PG&E customers; ~35,000 still without power Sunday morning (per SFGate). |
| Waymo ride volume | Approximately 450,000 robotaxi rides per week, per a leaked Tiger Global letter. |
Why this matters
- Large-scale infrastructure failures expose how autonomous fleets handle non-standard traffic conditions.
- Waymo's handling shapes public trust and regulatory scrutiny for urban robotaxi deployments.
- Operational lessons from outages will inform future safety and routing algorithms.
Pro tip
Monitor official Waymo updates and local transit advisories during major outages to avoid stranded trips and unexpected delays.
FAQ
Did Waymo suspend service because of the blackout?
Yes. Waymo temporarily suspended service in San Francisco during the blackout and later resumed it once systems and conditions allowed.
Why did robotaxis stall at intersections?
Waymo vehicles treat dark signals as four-way stops. The widespread outage created complex intersection scenarios that caused some robotaxis to pause longer than normal while assessing safe actions.
How widespread was the blackout?
Reports indicate about 120,000 PG&E customers experienced outages, with thousands still affected into Sunday; a PG&E substation fire appears to be the cause.
