So you're comparing the very first prototype cars to the technology present in millions of Teslas? Seems like a very contorted analogy and makes no real sense.
We are specifically talking about people who signed up to be a beta tester.
FSD is not a rational choice over the alternative and its adoption in no way resembles the adoption of cars. The analogy is bunk. But I won't keep beating a dead horse here, I was just trying to explain why it doesn't IMO make sense.
