It was a nice concept but videos have made it clear for some time the internal roadway wasn't happening. The west structure will connect eastward within a week or two.
How does that preclude the internal road? The ground floor ceiling is much taller than a semi, and the spacing between posts is much wider.
Yeah, the internal floor is all at the same level. When you load/unload a truck you want a difference in level between the road the truck is on and the dock. Like 4-5 feet. That's clearly not happening inside the factory.
For standard goods in a trailer, sure. Bulk materials that get unloaded from the side or via gantry crane (steel rolls, aluminum) are less compatible with that setup. Expanding on efficency, the use of shipping containers would allow rapid swapping via crane. Trucks would only be there for the time it takes to switch units. Then the container gets unloaded as needed.
