WASHINGTON: Uber had disabled an emergency braking system in a self-driving vehicle that struck and killed a woman in Arizona in March even though the car had identified the need to apply the brakes, the National Transportation Safety Board said in a preliminary report released on May 24.
The report into the first fatal crash caused by a self-driving vehicle also disclosed that the modified 2017 Volvo XC90's radar systems observed the pedestrian six seconds before impact but “the self-driving system software classified the pedestrian as an unknown object, as a vehicle, and then as a bicycle with varying expectations of future travel path”.
