Several reasons, but again, it is just guessing that cannot replace actual data. That doesn't mean we should take the only data point available (90 million miles) and declare it settled.

Your point about people seeking to drive faster is a valid one.

The counterpoint is there are people who cannot afford luxury cars but also want to drive faster -- they'll end up buying cheaper cars that can drive fast within their price range. Those are likely to be more fatal than the average luxury car.

1) Hypothesis on car age. An accident on a 2002 non-luxury car model is supposedly more likely to be fatal than an accident with your average new car.

This matters because Teslas with autopilot are relatively new compared to overall car population.

2) Hypothesis that low cost cars are more fatal than an average luxury cars.

3) Demographic hypothesis. Because of price point, the buyer demographic of newer luxury cars will be different than the overall demographic. Age group (e.g. teenagers vs. young adults vs. older adults), education level, profession.
