Every modern used car on every lot in the country still has the previous owners phone book transferred via Bluetooth along with their navigation destinations and probably garage programmed too. This isn’t new or unique to Tesla.
Most modern vehicles have event data recorders built-in. The video is somewhat new, but other new vehicles have built-in dash cams as well including GM vehicles like the Corvette which has had it since 2014.
And many rentals too. It's easy to hit yes transfer contacts when you pair to play music...then forget to wipe before you return it. Easy to sleuth who that person likely was based on their contacts...and their favorite strip club.
Not that wipe always wipes. In my second hand BMW i3, I wiped it to delete the last owners contacts. The wipe missed one thing : the map locations it was charged at. Likely that included their home.
Ideally there's a standardized wipe feature that really does it.
And wouldn't encypting this require the user to enter a password on each trip where they want to make use of the info?
Ultimately it doesn't strike me as unreasonable for the user to need to wipe their info from their car when they sell/scrap it, just as they need to remove their physical belongings from the interior. (Although I'm sure things could be designed better to make the wipe process easier to accomplish and harder to forget.)
