Waymo robotaxis encountered significant operational disruptions in San Francisco on July 4, resulting in multiple vehicles stalling, depleting battery power, and requiring towing due to severe holiday gridlock. The incidents followed unplanned road closures and dense congestion associated with the Golden Gate Bridge fireworks display in northern San Francisco. User-generated footage circulating on social media depicted Waymo vehicles immobilized in traffic jams, with one report capturing a robotaxi driving through an erupting box of fireworks. User Marco Gutierrez highlighted the operational impact, noting that disabled vehicles caused towing delays of three to four hours while blocking traffic. Waymo spokesperson Chris Bonelli confirmed that extreme traffic density disrupted normal fleet operations. Bonelli stated that the company's autonomous vehicles became stuck in the standstill, and several depleted their batteries while idling. Waymo emphasized that all vehicles operated fully autonomously utilizing a multi-sensor configuration comprising 29 cameras, five lidars, and six radars, and that no injuries were reported. The Alphabet subsidiary coordinated with local authorities and emergency services to deploy roadside assistance, clearing disabled cars from the roadway. While some robotaxes managed to navigate away once congestion cleared, others required towing logistics managed by Waymo's recovery team. The company acknowledged the challenges and noted it is evaluating protocols to strengthen fleet resilience against major traffic disruptions. Waymo currently operates approximately 2,500 autonomous vehicles across multiple U.S. cities.
