My wife and I have 2 teslas, a HW3 and a HW4. Even late last year FSD 12.5 was nowhere near close to being able to drive safely. Any non-straightforward situation (like merging during rush hour) would throw it off, so critical interventions were required at least daily.

Starting with FSD 13 on HW4, which came out last December, it's improved dramatically, and since then in my case it hasn't needed a single critical intervention. I think 12.6 on HW3 is also quite good.

The caveat is that we live in the Bay Area, which has an abundance of Tesla training data. Elsewhere I've heard the experience isn't as good. And of course, even in the Bay Area the reliability needs to get a few orders of magnitude higher to be suitable for fully unsupervised self-driving.
