The idea popped into my head today of using some sort of Bluetooth relay devices to unlock a Tesla. Thief A stands near your car, thief B stands near you (in the mall, grocery store, etc), each with a device that relays the Bluetooth exchange between your phone and vehicle.
After a bit of Googling, it seems this can't be done easily with standard off the shelf devices, or at least not that I could find. Certainly it must be physically possible though, it's just relaying short-range wireless signals back and forth across a longer distance.
PIN to drive would be the other challenge. A brute-force device that mounts onto the MCU and rapidly types all PINs would be one way. It would probably take a few hours to go through all possible PINs though. Really, if you have a good view of the car while the driver is typing the PIN, it seems like it'd be easy to get. Probably this would just take a good targeted attack (follow the driver on their travels, binoculars, write down the pin).
I'm going to steal *all* of your Model 3s... then I'll park them all at my house and send a mass TXT... "surprise, I've got your car!". Really it'll just be a fun way to invite you all to a Model 3 owners backyard barbecue party. Except you'll all need a ride... haven't figured that part out yet.
