That video was clearly faked, I mean it wasn't even faked very well. You can even see how FSD wasn't enabled at one point you can see the car flashing warning signs (but the audio of course was removed so people wouldn't notice). The driver manually over-wrote the system and that behavior is clearly explained in the user-manual and its how the car is supposed to work.
Do you always take internet videos made by literal competitors over the state licensed regulators?
