As discussed above I'm pretty sure buying FSD improves their cash position but doesn't count as revenue (or maybe they count some small % of it?). So if you give them $6000 today, they have $6k more in the bank, but that money does not increase the profit they report (or rather, reduce the loss).
I'm so on the fence about buying FSD. I already have standard auto pilot (came with my dual motor non performance Model 3 that I presume is HW3 based on the fact that I got it in late May). I would like the functionality of Navigate on Autopilot right now, I just wish I didn't have to pay so much for the current feature set.
I keep thinking about two sayings that my grandfather and father would tell me.
1. "Deals are for people with money" i.e., I can afford it, and if Elon is to be believed, I will be saving money in the long run by buying now.
2. "A fool and his money are soon parted" i.e., don't believe the hype, don't be a sucker.
I can definitely afford it so it's more about should I get it or not. I'm also debating waiting until V10 comes out to see how that is working out.
