Every Tesla leaves the factory with FSD hardware, but software activation depends on regulatory approval. Because FSD isn't fully approved in markets like China or Europe, a grey market emerged. Hackers developed CAN bus modules that plug into the vehicle's "central nervous system."
These small USB-style devices "spoof" the car’s location, tricking it into bypassing software locks. Reportedly, Tesla disables hacked FSD as over 100,000 cars use illegal mods in China alone. These modules typically cost between $700 and $2,000, offering a shortcut to advanced navigation and Smart Summon features.
