Which leads to mapping failures being unchecked, as the system that generated the data is the one checking the data by driving it. See bullet point 1 in their recent recall for an example.
> Prior to the Waymo ADS receiving the remedy described in this report, a collision could occur if the Waymo ADS encountered a pole or pole-like permanent object and all of the following were true:
> 1) the object was within the the boundaries of the road and the map did not include a hard road edge between the object and the driveable surface;
> 2) the Waymo ADS’s perception system assigned a low damage score to the object;
> 3) the object was located within the Waymo ADS’s intended path (e.g. when executing a pullover near the object); and
> 4) there were no other objects near the pole that the ADS would react to and avoid.
