That’s what it will take for you to believe that someone has gone thousands of miles without intervening? I don’t think that even Waymo (which has thousands of vehicles that have gone much farther without human intervention) has met the criteria you’ve set.
Happily, I don't care about Waymo. I do care about statistical competency among the population. Everyone should know that a single data point is irrelevant, as it could be noise just as easily as it could be signal. It is statistically insignificant.
You can actually do the math to find out the sample size you would need to derive a statistically significant conclusion. No need to be incredulous at my answer to your question: it's basic statistics.
As an aside: in general, if you find yourself going to a single person for data and expertise, you might be falling victim to a personality cult.
If one person can do this then thousands should also be able to.
