Autonomous vehicle operators like Alphabet Inc.-backed (NASDAQ:GOOGL) (NASDAQ:GOOG) Waymo were slammed by San Francisco Mayor Daniel Lurie following multiple incidents and disruptions involving Robotaxis in the city.

Daniel Lurie Demands Framework For AVs According to a report by the SF Chronicle on Thursday, Lurie decried a traffic jam during San Francisco's Fourth of July fireworks show when More than 100,000 people were present in the city's northern waterfront, which led to gridlock as dozens of driverless vehicles stalled in travel lanes and parking areas, the report said.

The congestion caused some Waymo robotaxis to run out of battery power while idling, blocking municipal shuttle buses and hindering emergency vehicle routes, the report added.

The incident marks another operational challenge for the autonomous driving leader, which recently recalled thousands of robotaxis over a software issue and had also suspended its services in the city following an outage at a Pacific Gas & Electric Co.
