Elmo faked a tech demo showing a new car that can drive upside down thanks to vacuum suction and can fly thanks to compressed air rockets.

Fine print: the car that goes on sale is not able to do that, only a very limited run that is sold to select customers at an unknown price (read: they don't sell it)

It's like if a robot company does a tech demo where a dancing robot is actually a human wearing a costume, or a bartending robot is actually remotely controlled by a human with a VR headset
