Take a look at a recent attempt of a couple of U.K. thieves to steal a Tesla Model S. They’re smart enough to actually gain entrance to the vehicle without the fob but they’re not smart enough to unplug the charger!
The owner of the vehicle does admit to not doing a couple of things that could have actually prevented the bad guys from gaining entrance including setting a PIN and using a Faraday pouch for the fob (while would block fob’s signal).
But it just goes to show that even “sophisticated” criminals who use technology aren’t always the brightest.
