I suggest that you do not make unwarranted assumptions, so as not to be disappointed. You really cannot estimate where you are in line, except that you are behind Tesla/SpaceX employees (though not necessarily behind overseas employees) and behind US West Coast and then US East Coast current Tesla owners who have a 3 reservation. You are likely behind Canadian Tesla owners. (Note: I think it has come out that about 7% of all Model 3 reservations are from current Tesla owners, I assume that is worldwide. Use that information as you will.)The one thing about the reservation system which I think they have to be transparent on, is where are the proverbial lines in the sand being drawn? I am just outside of Toronto, and approximately 105,000th in line, given that I ordered online about an hour before the reveal
That is all I can say with any degree of confidence. Whether that makes you 30,000th in line, or 200,000th in line, I have no idea.
