The National Transportation Safety Board has released its preliminary report on the fatal March crash of an Uber self-driving car in Tempe, Arizona. It paints a damning picture of Uber's self-driving technology.

The report confirms that the sensors on the vehicle worked as expected, spotting pedestrian Elaine Herzberg about six seconds prior to impact, which should have given it enough time to stop given the car's 43mph speed.

The problem was that Uber's software became confused, according to the NTSB. "As the vehicle and pedestrian paths converged, 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," the report says.
