Here is likely glimpse of the future:
It's 2020. Google/Waymo has a fleet of 50K-100K autonomous cars on the road. Elon announces new AP4.0 with second generation Tesla chip capable of FSD, after all the software validation and government approval of course, which is impossible to predict when. During an investor call someone asks about AP2 customers, Elon says "Booooring.... Next!". Tesla releases a statement how AP2 is fully capable of FSD but limited by lack of sensors, required redundancy of sensors and controls, and computing power - but otherwise all capable. They get sued in Europe and settle. Fanboys come to defence "Elon never said the car will actually ever drive itself, only that car is capable, which it is". Sound familiar? That's because it already happened with a different feature once.
