The comparison to human crash rates needs more context. These low-speed incidents (1-4 mph backing into a fixed object) rarely get reported in human driver statistics because they usually do not involve police reports or injuries. The NHTSA SGO database counts all ADS incidents regardless of severity, while human driver baselines come from reported incidents.

That said, the redaction issue is the real story. Waymo publishes detailed narratives. Zoox publishes detailed narratives. Tesla marks everything confidential. When every other company is transparent and one is not, that tells you something about what they are finding in the data. You cannot independently assess fault or system failure, which makes any comparison meaningless.
