Amazon’s autonomous vehicle unit Zoox recalled over 270 robotaxis after a crash involving an unoccupied vehicle in Las Vegas on April 8, according to Reuters. The company halted operations following the incident, conducted a safety review, and issued a software update. Zoox disclosed that its software may fail to accurately predict slow-moving perpendicular vehicles, increasing crash risk. The recall highlights ongoing challenges in the U.S. autonomous vehicle race, where Waymo, Tesla, and Zoox are leading development.
