I was having a good look at the "My Tesla" page, and in the source html there appears to be reference to two unique identifiers in addition to the RN number which is displayed on the page. The first is called "uid", and is an 8 digit number. The other, more interesting one is called "ReservationId", and is a six digit number. My number was "3xxxxx". I wonder if this an actual indicative reservation number based on the parameters already made public (Date of reservation / region / existing Tesla owner). Can anyone who lives near Hawthorne have a look at their page and see if their "ReservationId" looks something like x1xxxx? Apparently Tesla/SpaceX employees get first dibs on reservations, but some reservation holders local to the factory should be in the first 20k. I'm quite aware that this could be utter nonsense, but thought it was intruiging nonetheless.
