I certainly don't think it was a car that flies. It could be a car that can do dangerous party tricks for no practical reason but I kinda doubt that do. Hell we live in an AI world now, why are you so confident it's what they claim it is, what in Musk or Tesla's track record indicates that this is anything but a hype effort?
If they used AI to fake a live demo in front of a bunch of people, that would be exceedingly impressive.
