This is the average for all cars on all roads, in all driving conditions.

To have a meaningful comparison, we would need to know the fatality rate for new luxury sedans on divided highways in good weather conditions.

Your statistic ignores the fact that autopilot is only used in relatively simple situations, and since you're measuring fatalities only, you need to compare it only with cars of equivalent safety ratings.

If you have statistics comparing humans and autopilot in relevant situations I'd be very interested, but the ones you quote are exactly the ones I'm complaining about as being nonrepresentative.

Even considering all miles equally, a rate of 1 per 130 million autopilot miles (a much too small statistic from which to generalise) still does not compare particularly well to a lot of cars driven by humans, e.g. the BMW 7 series.

Incidentally, it's not at all clear that the situation described in your anecdote even involved the autopilot functionality, as it sounds like it was autonomous breaking which is a standard feature on many cars.
