Pedestrian in self-driving Uber crash probably would have lived if braking feature hadn’t been shut off, NTSB documents show

A pedestrian killed when she was struck by a self-driving Uber SUV last year probably would have been saved if the company had not disabled the automatic emergency braking feature that came with the vehicle, according to new documents released Tuesday by federal investigators.

Uber retrofitted the Volvo XC90 with sensors and computers as part of an aggressive bid to make quick progress in the highly competitive world of autonomous vehicles. But to avoid interference with its self-driving testing on public roads, Uber actively blocked the Volvo from slamming on the brakes in an emergency.

However, documents released Tuesday by the National Transportation Safety Board show Uber’s self-driving system was programmed using faulty assumptions about how some road users might behave. Despite having enough time to stop before hitting 49-year-old Elaine Herzberg — nearly 6 seconds — the system repeatedly failed to accurately classify her as a pedestrian or to understand she was pushing her bike across lanes of traffic on a Tempe, Ariz., street shortly before 10 p.m.

Uber’s automated driving system “never classified her as a pedestrian — or predicted correctly her goal as a jaywalking pedestrian or a cyclist” — because she was crossing in an area with no crosswalk, NTSB investigators found. “The system design did not include a consideration for jaywalking pedestrians.”
