According to statistics that Tesla publish.
I would like to see mercedes publish their own statistics on their FSD. Given the tight constraints where they allow self driving, they could easily claim 100% safety record and thus infinitive more safe than any other manufacturer. It would be misleading, but statistically it would be the truth (any accidents could be said to be outside the constraint and thus will not count).
Personally I would only really trust such statistics if insurance companies would reflect that in the premium. Somehow I doubt they would be willing to cut the fee based on what Tesla claims.
