At 12:46—13:13 there is some wasp-wasting to the wake after it is abaft the bodywork with no sign of a trailer. How does that work?

Hucho presented 2-D schematic representations for square-back,notchback,and fastback wakes.There's a peculiarity of the square-back wake in which the turbulence forms a repeating,cyclic vortex street if you will,resembling tumbling Easter Island Moai,after falling from the moving vehicle.This really shows up at El Mirage Dry Lake,behind squareback racers.The air just has a conniption fit back there.And it extends for hundreds of feet behind,until viscous attrition wears it down to nothing.Pure entropy!
