Why do you think the accident rate is lower among luxury cars as compared to more common vehicles? I would suspect the opposite. My hypothesis is that the people who seek out and buy cars that go 0 to 60 in 3.2 seconds probably drive faster and more aggressively than average. They therefore are more likely to have an accident.

Highly unscientific anecdotal evidence and personal experience living in an area with an unusually high concentration of such cars shows me that most people that own really fast cars do drive fast and enthusiastically from time to time but do so in a responsible manner and typically respectfully go with the flow, whereas a lot of people with more regular cars (mostly MPVs around here) have a habit of driving a good deal too close and a good deal too fast every single day. Many even engage in some truly reckless behaviour as soon as they feel threatened/frustrated, a telltale sign of power/control issues.
Very anecdotal evidence here commuting in Toronto here:
- more drivers in $80k+ cars leave 2-3 times the following distance than other drivers with cheaper cars.
Not all, but very noticeable sometimes.
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.
Luxury cars do tend to do pretty well among late model cars in terms of fatality rates--haven't seen rates for accidents overall. But the biggest correlation is probably that bigger cars are safer and smaller cars less so:
But this is overanalyzing, if we use only the "1 fatality in 130 million miles" stat. That 1 fatality was a car driving under a truck at speed and losing its entire top half.
I don't think more expensive cars are less likely to have that kind of accident, nor would it be less fatal.
I'd wager that if you compare it with cars at Tesla price point -- mostly luxury cars -- Tesla would look pretty bad.
