If you really want to remove the 'big corp spying on you' aspect of Teslas, you can always pull the SIM card or ask for the non-SIM version.
It's apparently an off-menu option, but you can request one without a SIM card, so effectively all the cell network stuff is disabled. Then, if you are worried about updates bricking something... just don't update it and never connect it to the WiFi? Seems like that gets you most of the way there.
