We don't have data on the intervention rate of Teslas, either. So far all you've presented is a single, non-statistically-significant anecdote.

>I think "miles between human interventions" is a useful measure of autonomous capabilities.

Exactly. What is Tesla's average miles between human intervention? The anecdote you presented is maybe 1/1000th of the minimum data you would need (of randomly selected participants) to answer that question. 1,000 is a bold claim, it requires statistically significant evidence
