The primary issue is that the data doesn't adjust for road classification in any way. Highway driving, where autopilot is used, has considerably fewer crashes per mile than city driving. Tesla compared Autopilot's rates against all driving rather than just highway driving which would be the relevant metric.
That adjustment alone almost completely eliminates any safety advantage of Autopilot before you get into any of the other adjustments like age.
Tesla’s data shows autopilot is safer (crashes less) than not on autopilot. The only question mark I’ve seen in this discussion is on NHTSAs data regarding Tesla.
Could you explain the flaw in Tesla data? How is crashes/mile not a good proxy for safety?
