The chairman of the National Transportation Safety Board says Uber had an ineffective safety culture when one of its autonomous test vehicles ran down and killed a pedestrian last year in Tempe, Arizona. Robert Sumwalt said at a hearing Tuesday, Nov. 19, 2019, on the March 2018 crash that Uber didn’t continually monitor its operations and it had de-activated its Volvo SUV’s automatic emergency braking system. Uber’s own system also didn’t have the ability to brake automatically, relying on a human backup driver to do the braking. (Tempe Police Department via AP, File)
