So they will diverge when the FSD re-write is release, then in time become the same again?It's currently exactly the same as FSD but with the total rewrite that's been announced some are speculating that it'll be different, personally I can't see tesla will want to have more code bases than they need and I'd guess that it will be easier for them to update/enhance FSD if they have data from the vehicles without FSD
You're probably right.
