FSD is not happening in the sense I mean it but it might in the sense you mean it. I mean “single-lane three-dimensionally-twisty-motorcycles-do-40mph roads covered in literal ice in complete darkness”. Because that’s what a large chunk of driving looks like around here. Even assuming no traffic and perfect understanding of the placement of the vehicle on the road (there’s no technology currently that can do that - no roadside markers, snow everywhere etc.) keeping it moving in the roughly the right direction without crashing would be a miracle of automation. But on a well-maintained California highway - sure, why not.
