If your simulation and regression testing is so bad that it can not be used to reliably validate 1 in 10,000 mile failure modes, then you are not ready to validate on public streets with untrained consumers. Tesla FSD routinely fails at 1 in 100 mile safety-critical failure modes. The simulation does not need to be perfect, it just needs to be 100x better than what they have and FSD needs to be 100x better before they should be allowed to inflict it on general consumers. If they want to test with trained safety drivers in a robust and well-controlled real world environment to identify failure modes that need to be addressed, that is fine. But non-criminal usage by consumers is at least a factor of 100x away.
