I wonder if maybe the 4 weeks is because they have not yet ramped up, and later invites, once things get going, might not take as long to deliver.
Are they maybe prioritizing people who are closer to the factory? That might put some day-two people ahead of some day-one people if the latter are farther away even within California? It's hard to believe they're just drawing names out of a hat. It certainly would be nice if there was more transparency to the process.
I live close to the factory, reserved on day one and have been an S owner for years. No invite yet. Just saying
