I think I found an interesting design change or style that will make the new Optimus factory at Gigafactory Texas visually look different from the main factory … the beveled angles on the ends of the buildings are different.
The main Gigafactory Texas factory has sharply angles beveled edges, but the Optimus Factory perimeter grade beam at the corners are curved.
Here is a comparison between similar points in the construction of both. This should be interesting if the final factory does indeed carry through these rounded corners.
What do you think?
