Sadly this is not the message you hear from Tesla salespeople.The FSD option in that Tesla is pre-selling something that is a complete unknown. Aside from tweeted estimates there is no official time table from Tesla, or exactly what it will do. I don't see much recourse a buyer has since nothing was really promised in writing. It just says it's up to software validation, and regulatory
The regular layperson idea of Tesla technology today is "oh! it's a car that drives itself!" (confirmed by FedEx delivery person that brought me my plates and asked me how is my self-driving car doing.)
Somewhat more educated public has this a bit different image of "Tesla has the most advanced 'autopilot' on the market that still needs some intervention from people, but they also demonstrated FSD last year and there's a video of it so it should not be too far away." (I fell into this camp at purchase time reinforced by salesman telling me that FSD is much sooner than I imagine and I might send my car to the service center for annual inspection all by itself (3 hours drive so hardly something I want to do myself)).
There was official eap timetable and that did not help much, btw (this is what the class action lawsuit is about). Needless to say salespeople did not acknowledge that one either. I.e. they demonstrated AP1 and said that AP2 is so much better, but they don't have any AP2 demo cars so just marvel at AP1 for now (happened to me on two occasions).
