Also don't undersell how wildly impractical this known technology is - it requires a skirt that in order to get close to the ground, which will abrade. It loses traction dangerously if the seal is broken, it's very loud and energy intensive. It sucks up dust, pebbles and other road debris and spits them out at other road users, and it takes up a lot of volume in the car. As do those thrusters.

This is a circus stunt.
