I didn't say that I knew. I was only disputing the relevance of defending individual Tesla crashes by saying that Tesla's are, on average, less likely to crash when on Autopilot. You can't compare Tesla drivers on Autopilot to all drivers -- you have to compare them to themselves, or you have an extraneous variable.

Fatal human accidents are on the order of 1-10 every billion miles of driving in the US, yes. Tesla Autopilot crashes seem to be much, much, much more common.
