But they made a mistake by announcing the design long before they were able to produce it. By the time they had built it, the hype cycle was over, and the design was already old news.
It was also supposed to be bulletproof (presumably looking like a tank), but in reality, it turned out to be a brittle underbody with glued-on panels that were peeling off.

The revolutionary new cheap Tesla batteries that were supposed to make that price point possible turned out to be as real as all the other stuff Elon promised.
