Is it going to be released at all, let alone on time? I'd bet against it. Tesla promises about future releases are worth dogshit.
Was the demo fake? I also doubt it. Tesla doesn't have a history of fake demos. It was only fake insofar as these were extensively planned stunts and they'll never be improvising maneuvers like that on the fly, as airplanes can. But was the car made out of CGI or sytrofoam? No. That's just painfully silly. Tesla has no track record of behaving like that.
