Musk: But... Aerodynamics!!!
Yeah, you kind of forgot something about that, too.
Laminar flow doesn’t really adhere to sharp angles, and spoils afterward.
I liked someone else’s comment, likening Cybertruck to the F117, and calling it the Impossible Diamond.
I wonder if this truck is only driveable with computer augmentation...

Where we're driving, you don't need side mirrors to see

you know, thinking about it, with the bed open, the wait will catch the back edge and make that ‘ball ‘ in the bed (mythbusters proved this in tailgate up/down fuel mileage
tests
Wonder if that has any noticeable
effect to help the air not spoil off that top edge.

Camera mirrors will probably be approved by then... But if not, I’m sure they can design some real quick. It will be real easy since they won’t want any curves on the mirrors.

Was the CyberTruck supposed to be merely a concept? Cuz I didn’t see any turn signal stalk, either . It better not be touchscreen-activated...
If only EssExTee could be so grossly incandescent

Usually it is a matter of degree, not eliminating trailing or void drag, but minimizing it, and creating boundaries. Kamm tails do that, not elimitating the void space behind the vehicle, but shaping it, maintaining and cleanly separating laminar flow, with a minimum of spoiling. The air-bubble in the bed of a truck can be similar, although not as clean as flow-managed aerodynamics.
In other places, a few spoiled eddy currents actually reduce trailing drag, by minimizing the pressure differential between the high pressure at the front of the vehicle, the flow across the vehicle’s sides, top and bottom, and the low pressure in the wake. Filling in the wake with some spoiled air can be better than very low pressure, or massively spoiled turbulent air.
Something as simple as adding a flatted facet surface to the roof, or heaven forbid, a curve., could preserve and manage laminar flow and drag management, rather than a sharp, turbulent edge.

Tesla really did a 180 from their previous, rounded designs.
