It strikes me as incredibly weird to maintain two separate stacks, especially because FSD was "available" when I bought my car. In retrospect, though, I guess it wasn't actually available to use, just for purchase.

So I suppose they had a parallel development process for FSD while building autopilot features?

But since there is a hardware support overlap, it seems like at some point you'd migrate autopilot cars to the FSD software stack, with limitations added in via feature flags.

Autopilot basically hasn't gotten any new features since FSD came out.

This is exactly what a lot of people speculate will happen soon.
