That's not quite accurate, the NHTSA study was not designed, in any way, to compare human-driven miles and autopilot-driven miles for safety. The only thing it showed was that vehicles with TACC + Autosteer had less accidents than vehicles with just TACC. Whether TACC + Autosteer is safer than human drivers is up for debate.
- URSpider94 9y agoTrue. However, it shows a very substantial decrease in accident rate in the population with Autopilot features, vs. the population without. Correlation, not causality. It could be that Model X drivers are inherently safer than Model S drivers (they would be in the latter set), or it could be that just having the features in the car makes drivers do better even without using them. However, the inference that Autopilot reduces incidents per mile seems very likely to be true.
