My phone and TV continue to work doing their primary job if I don't have them attached to the Internet. My Google Pixel 5 Pro will continue to operate as a phone only if it is removed from Internet and unable to install updates or check into the Google Mothership. Same with my Sony TV. Yes, they lose some functionality because they are not on the Internet but I would expect that because those functionalities require the Internet. However, my car should always work as a car, even without Internet access or ever checking with the Car Manufacturer Mothership. Yes, I can expect mapping feature to not work, but when I start my car, it should always start.
