Google it and you’ll see tons of websites telling this was faked.

E.g. that it’s highly illegal to stop a car on the road, contradictory information on tesla display (failed update and cease and desist, don’t go together. Also return to dealer while being disabled?), addressed name in letter is not the real name, hyphen in wrong place, etc. And tesla (obviously) claimed it’s false.

I’m not saying this is proof but saying there are a lot of red flags. Any update from him? Not that I could find. A stunt perhaps to gain publicity?
