Uber self-driving car saw pedestrian but did not brake before crash

An autonomous Uber car spotted a pedestrian about six seconds before fatally hitting her but did not stop because the system used to automatically apply brakes in potentially dangerous situations had been disabled, US federal investigators said. In a preliminary report on the crash, the National Transportation Safety Board (NTSB) said emergency braking maneuvers are not enabled while Uber's cars are under computer control'to reduce the potential for erratic vehicle behavior'. Instead, Uber relies on a human backup driver to intervene but the system is not designed to alert the driver. Investigators examine a driverless Uber SUV that fatally struck a woman in Arizona. The National Transportation Safety Board (NTSB) said emergency braking maneuvers are not enabled while Uber's cars are under computer control In the crash in March, the driver Rafaela Vasquez began steering less than a second before impact but did not brake until less than a second after impact, according to the preliminary report, which does not determine fault.
