Not mentioned in the article is that the truck isn't built as originally promised. The exoskeleton was supposed to do away with the need for an internal frame, giving it weight and cost advantages. Turned out they couldn't make it work for production, so it's built like a normal vehicle. A normal carmaker would have shown the cybertruck as a concept, and the final product would have whatever compromises necessary to make it a successful production car. Tesla promised it would look exactly like that and took deposits, so they stuck with the weird design even after the engineering reason for it was gone.
