The reason I'm using a single example is because we don't have comparable statistics across manufacturers, and because it's enough to demonstrate my point about Tesla's autonomous capabilities versus other brands. I am saying the same thing you are: Examples exist of FSD being used for thousands of consecutive miles without intervention. But you cannot find such examples for any other consumer car brand today. If Blue Cruise, Super Cruise, Mercedes-Benz Driver Assistance, or any other technology went similar distances without any human intervention, then it would be accurate to claim that, "Other brands have had self driving features for years now. Some even operate at a higher level of automation." But we don't have such examples, so it's not accurate to make such claims.
Nowhere in this thread am I claiming that FSD is safe enough to be used without human oversight. I'm also not claiming that Tesla has delivered on their promises (they obviously haven't). I am comparing the capabilities of autonomous systems using evidence that is publicly available. Since we don't have comparable statistics across manufacturers or some sort of standardized road test, I think "miles between human interventions" is a useful measure of autonomous capabilities. That's what has been used to demonstrate safety of other autonomous systems, and I see no good reason why such a metric should be ignored in this case.
