I found this old thread: Car battery thefts from hybrid cars on the rise in San Francisco This applies to both S/X but posting in the S forum since that's what I have. With more and more people hacking Model S and X it could be that a aftermarket shops start to do interesting things. Maybe even fitting bigger/new battery packs in older cars. Now, it's not so hard to remove the battery of a Model S/X. Jack it with 4 jacks, put a trolly underneath it and unscrew the battery. Do we think we will see batteries being stolen from Model S/X out there?
