If you're waiting for a car, the only thing that is a true indicator of an impending delivery is an assigned VIN. Knock yourself out trying looking at the source code, the only signal that will confirm that your car has been built and is on the way from Shanghai is an assigned VIN. Based on past experience, this place is likely to light up with people confirming they've got VINs assigned around 15th July.
Don't think of it as a queue but rather a delivery cohort. Tesla don't have a method whereby an order pulls a build through the system (which would allow you to know NOW when your car is scheduled to be built in the future), but rather build in batches for markets. Those in Aug-Nov are hoping for VIN assigned in mid July for a mid August delivery, otherwise there will likely be a second ship in Q3 to deliver cars by end of September. Without a VIN, nobody can confirm a thing.
