Well, I think that is also morally reprehensible in all other cases where it's also a matter of activating software safety features.

Most of the things you mentioned aren't software locked behind a paywall, hopefully, you don't swipe your credit card and get those features added via OTA in minutes. If your car doesn't have back seat airbags it's hopefully not because you haven't paid for the back seat airbag in-app purchase.

Okay you are correct. If they are going to market FSD as a safety feature and it's just a software update, they need to include it by default and adjust their price.

I didn't realize how much they market it as a safety feature.
