旧金山大停电，Waymo自动驾驶汽车瘫痪，特斯拉赢麻了

Core Viewpoint - The article discusses a significant power outage in San Francisco that led to the paralysis of Waymo's autonomous vehicles, highlighting the vulnerabilities in their operational design compared to competitors like Tesla [1][2][20]. Group 1: Incident Overview - A large-scale power outage occurred in San Francisco due to a fire at a Pacific Gas and Electric Company substation, affecting approximately 120,000 users [1]. - During the outage, Waymo temporarily halted its services, and numerous autonomous vehicles were seen immobilized on the streets, causing severe traffic congestion [2][3][4]. Group 2: Technical Implications - The power outage resulted in traffic signals being non-functional, leaving Waymo vehicles confused at intersections without green lights, leading to prolonged stops [18]. - Waymo's autonomous driving system is designed to treat non-operational traffic signals as all-way stops, but the scale of the outage caused these vehicles to remain stationary longer than usual [18][19]. Group 3: Competitive Analysis - In contrast to Waymo, Tesla's Full Self-Driving (FSD) vehicles continued to operate normally during the power outage, demonstrating a more robust handling of unexpected situations [20][21]. - This incident underscores the advantages of domestic automakers' approach to intelligent driving, which is moving away from heavy reliance on high-definition maps and strict constraints [24].
