It's kind of a hybrid.
Much of the wheel is shielded, however the outer face retains the gap mutilation and partial windage.
The rear suspension looks a bit like a torture chamber for the side flow, contaminating the onset flow to the tail.
Baron von Koenig-Fachsenfeld made his name, winning a race, by removing an impotent boat-tail like this from a Mercedes' racer. It was offering no drag reduction, only added mass, and aggravating the polar moment of inertia.
I suppose one could try
blowing the acrylic, but pros typically vacuum the heat-softened plastic into a break-away, perforated wooden tool of desired geometry. It's the only way to guarantee the optical purity of the screen.
It would never pass DOT requirements for a road car.
The tooling for a DOT laminated windshield for James Bedes' small 'jet motorcycle' was $ 10,000 in 1980 dollars.
'sucks to be poor!
