> "I'll do 99.90% of it correctly, you watch and catch the 0.1% when I screw up!" style systems that rely on the human to catch the mistakes shouldn't be permitted to operate in any sort of safety critical environment. It simply doesn't work. Right, because it actually relies on the human to catch 100% of mistakes _anyway_. The human can already do the 99.90% of it correctly with a reasonable degree of safety. I wouldn't be surprised if the increased cognitive load on the human in such a system is an actual overall decrease in safety and strictly worse than a human operator alone. At least with an unreliable system that Tesla demonstrated here.
