As explained by the sales guy, this does nothing for now and is just a SW upgrade so we could to it later when/if the car is suddenly able to drive while I nap. He also seriously oversold the self-driving capabilities ("it's capable of driving itself from NY to LA, that's just not legal yet"). Thoughts on declining this? It it really nothing but a SW option that can be added later? If FSD ends up requiring HW upgrades, am I passing on that by not taking the option now? Is Tesla really selling an option that does nothing at the time of sale?
