The lists are interesting. And for me they are mostly telling that they are all in some super early prototyping phases. E.g. Tesla lists tests with < 600 miles with 4 cars in a year. Mercedes 670 miles with a single car. The only outlier which really seems to do serious testing is Waymo with 630k miles.
To give some comparison numbers how normal series cars are tested at bigger automotive companies: There are test fleets of partly over 100 cars for a new car model, where some of those are tested all around the clock (> 600 miles per day). All in all often 2digit million kilometers.
