I didn't say it wasn't ok to be skeptical, just that I wasn't surprised by the results. Teslas have been on the road for over a year with AutoPilot and there haven't been any accidents caused by the system. Why anyone is surprised that AutoPilot is safer than a human driver is what I'm not understanding. Based on the votes, though, apparently computers are evil and shouldn't be trusted and we should all be amazed when they don't just kill us.
You said you didn't understand why it was surprising, which is a different thing than not being surprised.
Computers are good at lots of things like playing chess, and still completely incapable at lots of things that involve common sense. Expecting autonomous cars to be better than human drivers eventually is one thing, but it is certainly not obvious that we are there yet.
