Not op but I’ll give my reply anyway fwiw.

$7k (x 2) at the time, reason was to help Tesla survive. Was not expecting anything else for my money in the next few years.

Nowadays Tesla’s survival seems more assured, so if I did it today, it would no longer be for that reason.

Some people pay for it thinking that it will be much more expensive later.

I question this thinking though, because once it’s possible, it will be a table stakes feature we take for granted on every car, which means it shouldn’t add a huge bump to the price. But maybe I’m thinking about it wrong.
