I get it, and that's my point. IMO those are the areas on which Tesla should be concentrating now. Infilling high population, areas where there are already "enough" chargers to for a through trip is not what I think should be priority.
Case in point, I did a road trip earlier this summer from Denver to Tahoe in an ICE car. Went via I-80, so all was good on charging there. But on the way back I decided to take a very scenic route that took me from the eastern edge of Yosemite, through the middle of Nevada and Utah before rejoining I-70. I have tried to route that trip nine ways to Sunday with a Model 3, and it's just not possible. But with one more charger in Ely, NV it would be.
As far as North Dakota and Lubbock are concerned, they are at least at permitting in ND. It appears that no permits are even pulled for Casper. And it is possible to get from either Midland or Sweetwater, both of which have SCs, to Amarillo via Lubbock.
