San Francisco Power Outage Knocks Out Waymo's Robot Taxi System, Authorities Downplay
JAKARTA - Last weekend there was a pretty gripping incident in San Francisco, United States when a massive power outage hit the city and caused a strike of a number of Waymo autonomous taxis.
This incident was widely reported on social media, especially X, where suddenly dozens of driverless vehicles belonging to Alphabet's subsidiary suddenly stopped in the middle of the road and at a red light intersection that was dead. In fact, Elon Musk even mocked this incident on X and boasted that a similar incident would never happen in Tesla's robotaxi.
The investigation into the incident is currently being conducted by the California Public Utilities Commission (CPUC) which is investigating the technical details of why the robotaxi fleet failed to respond appropriately to the emergency situation on the ground.
Launching Reuters, Tuesday, December 23, this traffic chaos began on Saturday night after a fire at the PG&E main substation cut off power to about a third of the city, affecting 130,000 residents. In the midst of darkness, video footage that went viral on social media showed a unique and worrying scene: rows of Waymo cars stuck at various intersections with hazard lights on. Without functioning traffic lights, the advanced vehicles actually stopped completely and created long traffic jams in the middle of the city that was in turmoil.
In response to the incident, Waymo explained that the "Waymo Driver" system was actually designed to treat dead traffic lights as four-way stops. However, the company admitted that the very large scale of the blackout caused their vehicles to remain motionless in place for much longer than usual. As a result of this uncontrollable situation, Waymo was forced to suspend all its operational services in the Bay Area on Saturday night before finally resuming operations on Sunday.
This incident has once again sparked a debate about the readiness of automated driving technology in the face of unexpected situations (edge cases) in the real world. Although Waymo has expanded its operational range to Los Angeles, Phoenix, Austin, and Atlanta with more than 2,500 fleets, technical constraints when city infrastructure is paralyzed prove that the commercialization of robotaxis still faces heavy regulatory and security challenges. Critics consider this incident as a reminder that even the most advanced sensor technology can still be confused by the failure of basic infrastructure.
As a follow-up step, a Waymo spokesperson expressed the company's commitment to integrating the lessons from this incident into its systems. The company promises to update its technology so that its fleet can better adapt to extreme traffic conditions in the future. On the other hand, the results of the inspection from the CPUC and the California Department of Motor Vehicles (DMV) will be an important determinant for the continuation of commercial autonomous taxi operating permits in the state.
