The fact that it's an obvious trick from a known snake oil salesman is a legit reason to think this is not "extremely cool shit". He's got an almost certainly hollowed out shell of a car and got it to fall slightly slower than gravity, but is selling it as a "flying car", and you're falling for it.
do think there's a danger of looking at extremely cool shit like a car driving upside down then doing a kickflip before landing, and convincing yourself it's actually lame because the guy funding it is a white supremacist
