What measure are you using for "slightly above average" that also equals "unproven dangerous"? If the above average technology is dangerous, surely the average driver is even more dangerous. Otherwise it's not really above average, no? I.e., how can you make fewer errors and be a measurably better driver but still be worse than the thing that you're measurably better than? Either you're making this argument in bad faith because you just don't like self driving cars, or you don't believe in statistics as a concept.
