Here is the Cybertruck* profile:
And here's Bild 112:
They aren't even close to the same contour. The curve between two points can take literally any shape--as we can see here with one curve and one line--and "matching" two points doesn't tell us
anything about the aerodynamics of this truck.
*First prototype;
video leaked last month purports to show a second closer to production-ready.
