How to reckon Tesla's Model 3 will sell globally
Pretty good, on a Tesla scale, but insignificant on a global scale.
Remember, even most optimistic projections put whole Tesla at about half the numbers of F150 sales - and that's just one model, sold pretty much only in North America.
It just so happens that Tesla is planning to take the model 3 global this year, they actually already started it in July they are taking it slow. It will be in these countries. From Elon's Twitter: "Adding several more countries to Model 3 order page tonight. Check for details, but will include India, Brazil, SA, SK, NZ, Sing & Ireland."
I also think that supercharges may come to these countries.
I think a lot of people will buy it because they want a piece of Tesla, but most of them will switch to the S, because a fully loaded Model 3 costs around 50k and still is pretty basic compared to a Model S.
If they don't pump up their production, people will drop out on waiting for it.
