There is a factor that is never mentioned. The actual "fleet" of Tesla (and of others experimenting in the autonomous vehicle field) is made exclusively of decently new and perfectly or nearly prefectly maintained vehicles. Besides and before any other consideration, the way a modern, newish and well maintaind car handles (steers, brakes, etc., particularly in an emergency situation) is hardly comparable with the way the "average" car can do, think of unbalanced brakes, worn down tyres, etc., but also about the undeniable truth that your - say - 1998 pickup won't ever be as stable as a sports car. Since there is no real data about the comparison term (all the other vehicles) status and capabilities (of both the car and the drivers), each and every comparison tends to be on favour of the Tesla for reasons that have nothing connected to the actual automation. Even an "internal" comparison (Tesla's on autopilot vs. Tesla's on manual driving) wouldn't be IMHO much representative as drivers of Tesla are I believe - if not an elite - a definite group of people, not too young, not too old, possibly with an interest or passion about cars, while "the rest" will comprise just licensed drivers (possibly with little experience and with a tendency to risk too much), elderly people (possibly with slower reaction times).
