I didn't get the Uber reference, have not they given up on driverless cars, at least for the near future? after the sensor / lidar failure resulting in a fatal crash.
It wasn't a sensor failure. Multiple sensors (including the lidar) detected the woman with plenty of time to stop.
It was a management failure. The car had a perfectly ordinary radar based emergency braking function factory fitted by Volvo but Uber disabled it, presumably to avoid interference with the cars autonomous driving functions (if I recall correctly).
