I wonder how is there no open data on "no mistakes FSD zones", e.g. areas of maps or routes that would be proven by large numbers to be error-free for Tesla FSD

I wonder how is there no open data on "no mistakes FSD zones", e.g. areas of maps or routes that would be proven by large numbers to be error-free for Tesla FSD without interventions. Would clearly show progress and make people understand when they're trying the road that's not proof yet.
