What I'm referring to when I say its not transferable is you can't trade your car in with FSD, and simply have Tesla transfer it to the new vehicle.
Lots of people including myself want it to be transferrable. Why should I lost money on something that I haven't gotten any real use out of?
What Tesla did with FSD before March 2019 was the functional equivalent of taking preorders for a physical product and not letting people update their shipping address while you're waiting for it to ship.
It's like if we bought a really good board game (EAP) and prepaid for what is claimed to be the greatest expansion to a board game in history, and 2 years later we got the dice for the expansion (stop signs and traffic lights), but the board and the rest of the pieces are still quite a ways away. We want to move to a new house since we're tired of the old one, but if we do, we have to leave the dice in the old house and they may or may not ship the rest of the game to the old house.
The new house comes with a demo version of the original board game, but it only has half the board and is missing a bunch of pieces. You can't buy the full version of the original game anymore because it's been discontinues, but if you buy the expansion, they'll give you all the missing pieces. Also, the expansion is more expensive now.
Except this still isn't crazy enough to actually match the FSD situation, because I want to buy the new F'ing house from the board game company, and the only thing stopping me from doing it is that they won't let me update that shipping address.
