I think you need 90 or above to actually get it. It took me three or four weeks before I got it. I live in New England, and our back roads are not very FSD friendly, so I have to really keep my hands on the wheel. It is definitely not for prime time yet. I am going on a 2000+ mile trip starting this weekend, and will try it more then, but the sudden braking on a clear divided road and occasionally jerking the wheel is a little unnerving.
Telsa offers FSD when you buy the car, but you don’t actually get it. I have my doubts that any Teslas on the road today will ever be able to Self-Drive reliably.
