I second this comment. Cybertent goes up quickly once you learn how, and I have 16" of clearance under the flat aluminum floor. I can put 6 tubs from Sam's Club under there without interfering with my bed.
My take is that this is way too optimistic in both numbers and dates. Elon has said that the full capacity at Giga Texas *aspires* to be 250,000 Cybertrucks. I don't think we will see that before 2025, and 2026 will be the first year they produce that number.
*Assuming* that Giga Mexico...
You beat me to saying this, and you did it better than I would have :) It is amazing how many folks, including some media journalists, who see "Cybertruck" and "100kw" and jump to the wrong conclusion.
