The promise was that you'd buy a Model 3 to use as your personal car, and then run it as a robotaxi while you're at work, and the taxi money would pay you back for the car within a year. FSD is nowhere near up to that task, neither technically nor legally. And the new info from this presentation is that it is, of course, never going to be: this was an indirect admission that the Model 3 was sold with fraudulent advertising by the then-CEO himself.
