The key phrase being 'generally'. Really advanced L2 assistance features that bleed into L3+ abilities like FSD work right up until they don't, then they hand control back to a driver who is not situationally aware enough to safely operate the vehicle. "Full Self Driving" is stretching those three terms far beyond the breaking point and Tesla should absolutely be slapped down by the FTC for false and misleading advertising.
If Tesla wants to take legal responsibility for the car while FSD is engaged they call it full self driving. Until then it's a dangerous beta test pedestrians and other road users didn't sign up for.
I like my tesla, but autopilot drives like a poorly trained teenager and I don't ever use it. FSD isn't much better and needs to be tested with proper rigour by trained employees of Tesla, not random owners.
