I'm sure you can come to a safe stop, and there have to be provisions for when not in mobile range because that does happen on occasion, but long term I wonder what it does for warranty or various features that might have (known or even unknown to tesla) dependencies on being online. I also seem to remember reading about a time lock, i.e. needing to be online every x time, but not sure.
