2. Elon's Trillion Dollar Payout is tied to a certain number of FSD Subscriptions.
3. Some consumers were sold that they would get hardware upgrades for FSD. I'm pretty sure Tesla would like to minimize that, and I expect incentives for those people to purchase new vehicle without FSD.
4. Subscriptions drive our economy, I don't know the details but it seems like every company wants subscriptions over one time purchases.
I honestly don't think they want a lot of people with lifetime FSD, it's disappearing without a lot of news.
