The car had LIDAR. It wasn't an equipment failure, it was a failure on the part of the programmers. They had programmed in a hard delay to prevent erratic breaking and the system was programmed to dump data whenever an object was re-categorized. The system detected the person in the road as an unknown obstruction and properly detected that it was moving into the road but it re-categorized that obstruction 4 times before correctly identifying it as a person. By that point, the velocity and LIDAR data had been dumped because of the re-classifications and the car only had <2 seconds to stop.
