On the 21st of this month (local time), a fire at a substation triggered a traffic standstill in San Francisco, California. The blaze erupted at a Pacific Gas and Electric Company (PG&E) substation, leading to a widespread power outage that rendered traffic lights inoperative. Waymo's autonomous taxis, unable to interpret the non-functioning traffic signals, came to a halt at multiple intersections, exacerbating traffic congestion to a significant degree. Blogger 'Bu Shi Zheng Xiao Kang' delved into the matter, identifying the core issue behind Waymo's unresponsive remote service: its autonomous driving system lacked programming to address scenarios where traffic lights are out of order. The blogger also recounted a test drive experience with Tesla's FSD v13 from the previous year. In a comparable situation, FSD seamlessly merged into the traffic flow, adhering to the principle of alternating passage. Finally, the blogger emphasized that for autonomous taxis to gain widespread acceptance, their models must be equipped with real-time reasoning abilities to manage non-standard scenarios effectively.
