No one wants to type in a code to start their car.
Every Tesla can be stolen with a basic technique...
step 1: Knock out owner while he's at a supercharger
step 2: Grab key fob and cell phone from owner and place owner in trunk or frunk depending on the size of the owner
step 3: Drive to your heart's desire or until you run out of juice... or until the owner wakes up and tries to crawl to the front of the car, doh!
step 4: Open trunk/frunk and give owner back his stuff and thank him for the joyride.
(you might be considerate and stop at another supercharger so he can charge up again and so you can wait for the next victim.. err passenger)
There's not really a market for spare Tesla parts so there's no reason to keep it and/or have it report its location. You can always use a jammer though to prevent cell, wifi, and/or gps.
