FSD licensing wont. A white swan has to be extremely extraordinary to the point that almost nobody expects it. For FSD licensing to have any real impact, first we need to have FSD working at lvl 5 autonomy with regulatory approval. FSD wont get to lvl 5 overnight. There have been and will continue to be so many frequent step changes to the software that it will almost be impossible to catch anyone by surprise. The stock might perform better over a long period of time as these positive changes are reported in the media. By the time FSD becomes lvl 5, it will already be old news as a lot of the SP gain will have materialized. By then, licensing will be just a natural step forward.
Right now, FSD licensing, if any OEM is crazy enough to go forward with it, is just going to be a pump and dump scheme. The software doesnt work yet. The cars have to be designed the Tesla way, meaning years and years of redesigns and a crap ton of investment for them. The money, just like NACS adoption, will take years to come in.
