When the large volumes of Model 3's arrive the whole dream of hundred of thousands of new orders comes to a halt when most existing Superchargers become long lines of frustrated waiting Tesla owners. Imagine with what glee the ev haters will flog that horse. That is how important the build out of the charging infrastructure is. It is not a sideshow, it is literally the future of the company. We are no longer talking about ev enthusiasts now, We are talking about convincing the skeptical general public about buying ev's. They have to get this going, and relatively soon! Once the current 400,000 + reservation holders for Model 3 have their cars, these Superchargers better be going up fast. Tesla will need the positive publicity of the public seeing Supercharger construction nearby in their local papers and newscasts to sell the tens of thousands new cars a month they plan on building for non-ev enthusiasts.
