In my opinion (so this assumes I could be wrong) until FSD is actually bulletproof, its take rate will be limited and there's no reason for other manufacturers to license it. I just don't see that many people desperate to pay such that they always monitor how the car drives. And even if they'd want to do it, what's the cost to add it to a legacy OEM fleet? Tesla has just a few car designs, BMW has probably over 15 body types, each with its own mounting positions for cameras. If we're talking new designs, then they'd need to integrate with BMW's suppliers for ADAS, another can of worms there. Totally worth it if it gets them level 4/5, but I don't see it being such a big seller for an L2 system, no matter how good it is.
