The NTSB investigation into the March 18, 2018 fatal crash in Tempe, Arizona found that the Uber test vehicle’s automated driving system detected the pedestrian about six seconds before impact, but repeatedly reclassified her - as an unknown object, then a vehicle, then a bicycle - and each reclassification reset the system’s prediction of her path. The car did not brake before striking her.
