With all of the telemetry, am I correct to presume that Tesla probably knows the current odometer reading for pretty much every car they've ever sold? So they could easily give out the denominator for the fatality rate in the original reporting? The total miles driven seems like it could be the weak link in the iSeeCars data, since I'm assuming they have to infer the total miles driven off of their used car sales data.
This should be looked into IMO. The Model S (and X, I think) were celebrated as getting the highest safety marks by a big margin. Either the safety ratings are garbage, Tesla’s manufacturing is substandard, or something else fishy is going on.
This reminds me of better doctors having higher fatality rates because the most critically ill patients seek them out. Since Teslas are at the top of every crash test safety study, I suspect that this is a spurious outcome of Simpson's paradox and that proper controls would make the effect disappear.
