More to not be able to pick up residual magnetism. And if things were encrypted as they should be, it would take one second to kill the key and poof goes the data. Love how the reset doesn't actually reset anything. Love Tesla QA.
Not sure what I would have asked Tysons to do if I'd known of this issue in March when I had this done (I was about the first one they did here in Northern Virginia), but yeah, perhaps delete home address, since that's about all I'd care about. Not that you can't google people....
