Value proposition would change somewhat if the FSD was tied to an account / person vs the car.
I am following some wise person's advice that i read somewhere on this forum. If you buy FSD now, you are buying an unfinished product. You subsidize further development of it by fronting the money, which is great for Tesla. However, if you believe in the company so much to pay 6 (now 7)k for something that is not yet fully function, why not buy 6(or7)k worth of Tesla stock and see how much it will be worth by the time FSD is actually useful. I am betting that stock will appreciate faster than the price increases on FSD as features mature.
