Autonomous vehicles have racked up a crash rate double that of those with human drivers. The glitch They obey the law all the time, without exception and humans don't. They usually get hit from behind in slow-speed crashes by inattentive or aggressive humans unaccustomed to robot motorists that always follow the rules.
Last year, Rajkumar offered test drives to members of Congress in his lab’s self-driving Cadillac SRX sport utility vehicle. The Caddy performed perfectly, except when it had to merge onto I-395 South and swing across three lanes of traffic in 150 yards (137 meters) to head toward the Pentagon. The car’s cameras and laser sensors detected traffic in a 360-degree view but didn’t know how to trust that drivers would make room in the ceaseless flow, so the human minder had to take control to complete the maneuver.
