I repeat this again and again, and am always surprised that nobody else likes to raise the unfair comparisons. I am willing to assume that waymo/Tesla etc have found the holy Grail, and made a driverless car safer than the average current human driver on the road. I'm not convinced that we should still allow these driverless cars on the road with no human backups. Not because of expectations or liability, but because the benchmark is wrong. We should compare them to a human assisted by the same driverless technology being used passively to prevent accidents. And it's not clear if a driverless car with no human backup is safer than a human assisted by the same technology.
