San Francisco is getting cold feet about self-driving car tests

Officials in San Francisco have asked for a halt to the expansion of driverless car tests across the city after a series of incidents that have hampered the work of emergency services. San Francisco's position at the heart of Silicon Valley and its wealth of technology talent has made it a hotbed for the driverless car industry. Both Waymo, owned by Google's parent company Alphabet, and Cruise, owned by General Motors, operate experimental robotic taxi services in the city. But they haven't been without problems. New Scientist has previously reported how autonomous vehicles (AV) from Cruise, for example, have randomly stopped and blocked traffic and had a run-in with police.
