I understand that buyers look at the supercharger map before buying a car. The vast majority of buyers in large metropolitan areas will look at their city, see x number of superchargers around their city, see that all highways leading out of the metro are covered, and see that the country (US in my case) in general is well covered for the most part. They may not know from the start that many of the Bay Area's (example city) chargers are often full. I guess once they find out it then helps customer satisfaction to build new superchargers. But how far will Tesla go with supercharger build outs before it starts to become less financially viable to build out more? Should there be superchargers every 50 miles on every highway? Every 10 miles? For me it would be nice if Superchargers were as common as gas stations but I know Tesla would not be able to afford that, since in essence the operational budget of the superchargers needs to be covered with a portion of their annual car sales, even though the superchargers not only serve the cars sold that year but the cars sold over the past 9 years. Sorry for the ramblings, I totally get the logic behind expanding supercharger locations. But there must come a theoretical point where they will have built and operated all the supercharger stalls they can afford even if coverage isn't 100% complete and if certain locations are still sometimes busy. I've always been intrigued by the financials of the Supercharger network, and when it makes "sense" for Tesla to build superchargers and when it doesn't. I suppose they probably have a formula for # of required stalls per x number of cars, etc.
