When you consider the traditional (i.e., old) process of buying a car from a dealership, you may come to realize that Tesla is probably doing it the right way by stockpiling cars in these temporary storage lots. For example, if you are looking for a specific vehicle with the color, interior and exteriors options you desire and it's not already in your local lot, more than likely that dealer can look on their computer and see if your configuration is at another local, or even remote, dealer. If so, they can then arrange to ship/swap cars. If one is not available, then you'll have to submit a custom order just like we've done with the Model 3. I'm assuming that you won't have to wait the 2+ years some of us here have.
Tesla can't do it this way at the moment since, 1) their stores/galleries don't have room to store the same amount of cars as a normal dealer (100's) and 2) they probably can't build a car with specific options one-at-a-time without having it affect their production goals. A related reason for these huge storage lots is the feeling I get, aka IMHO, that they also support a desire to game the system for maximizing the number of customers that can qualify for the full federal tax credit. Since we now know that the $7500 credit will last to the end of this year, Tesla is trying to deliver as many vehicles as they possibly can (e.g., 5-15 minute delivery schedule). Tesla's problem now is matching up demand with supply, along with trying to maintain QC.
From reading several horror stories here about people still waiting for their cars after ordering them
months ago, and reports about what I consider infant mortality fails, I really hope that these are outliers. It's a given that reading posts on forums like this highly magnify negative experiences over positive ones. If you're satisfied with your ordering and delivery process and your car is defect-free and performing as expected, you'll be out driving it around enjoying yourself, rather than signing onto a discussion forum and saying how great the car is. And yes, there are outliers in this case as well
