Averages are a bad way to look at the overall risk.

An example:

  Every time the auto pilot encounters a truck turning in front results in a fatality.
  1 in 10 times a drunk driver fails to avoid the truck turning in time.

The average overall for drunk driver could be 1 in 50 million miles and the auto pilot 1 in 90 million, but you are certain to die in a few instances with the auto pilot, but the human could possibly save himself in the same situation. I imagine the Tesla has lots of these bugs that haven't been found yet.

I would trust a drunk driver over Tesla's autopilot at this point. Don't die for Elon Musk's dream--being one of the first auto pilot fatalities isn't that big of an accomplishment.

Also, I'd give "Technopoly" a read.
