I ordered mine one day after you and my EDD of 9/4 - 10/9 has been unchanged for over 3 weeks. I'm taking delivery in St Louis which is near the general region as yours. Those Tesla loaded train cars from Fremont likely go to Chicago then break out to SC in the region. Hopefully I'll get mine a few days after you get yours likely in early Sept. That would fit with the 8 week delivery window from OD that most people are averaging on MP3.
That is except for Flatbroke
That 8 week window is long gone! If I was living that close to Fremont, I'd be camped out at the factory car exit door saying like a rabid zombie over and over again "Is that mine?"
