True. 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.
