Would you pay a yearly fee to continue getting updates for your now no longer being updated but perfectly fine otherwise phone? I would.
Good question. At that point I’d explore replacing the OS altogether with GapheneOS or LineageOS.
When it comes to cars though, I don’t find FSD an appealing enough value to continue paying (or even begin to pay in the first place). But to your point, that doesn’t mean Tesla shouldn’t price it how they want and people to buy it if they wish.
