But those levels are kind of bullshit. If a car is autonomously driving but needs an attentive driver in the seat for legal reasons you're stuck at what, level 2? Even if you never actually need to override/intervene?

Teslas running the latest hardware (manufactured 2023+) and software are actually nearly there, IMO. I used it for two months and never needed to intervene. It's not perfect yet but I believe it actually drives better than most people now.

However, the millions of Teslas on the road with older hardware are absolutely useless in comparison where you will need to intervene a lot. The latest FSD software only works on the latest hardware so these older cars are stuck on either old FSD versions (which are proven to be bad) or get slimmed down versions to fit lower specs (which we know wont be as good). It's unsafe and they really should disable it for all of the older vehicles and issue refunds for people who paid for FSD.
