Finally some light on this. Excellent article, really impressed by MT:

“The plusses for a folded stainless steel, origami truck are compelling: no paint shop and no expensive tooling”
“... Ditch the heavy, traditional, body-on-frame, and rethink the structure as weight-efficient trussed bridge in its simplest load-spreading configuration: a triangle set on its hypotenuse. One side is the Cybertruck's wedgy cab, the other, its tapered, sail-sided bed, their meeting point at the truck's tall peak resulting in a huge cross-sectional area for maximum stiffness.”
“... But the aerodynamics of that peaky profile?
It almost looks like a deliberate, suicidal attempt to trigger boundary separation—a potential drag-raising catastrophe for limited-energy EVs. And an odd 180 turn from the Model X and Y, which have such delicately arched profiles precisely to avoid drag-raising trip wires like this.
Tesla might have erased the problem with active suction to bend the boundary-layer downward just aft of that peak. Gordon Murray's McLaren F1 used this trick, and SpaceX has plenty of expertise in active measures to manipulate airflow around its re-entering Falcon 9 first stages.”
