Tesla has a huge dealership…
Tesla has a huge dealership / storefront in northwest Houston, Texas that is stacked full of Cyber trucks (presumably unsold), which backs up the claims in this article. The dealership parking lot is full (of vehicle stock), and they're storing the excess on a grassy field adjacent to it. So many Cybertrucks that you could probably identify them from satellite images (assuming you're looking at current images). Makes sense that they can fulfill orders quickly.
