Back when there was only ONE supercharger in the entire country, wifey and I drove from San Francisco to Coeur d'Alene. We used RV parks, enjoyed taking walks while the car charged, used motels that had RV outlets, and had a great time. Now, I own the Model S Long Range and get near 400 miles on a charge. Can't complain. What I see is most people want lots of range FOR LESS MONEY. This takes time., but with Superchargers almost everywhere, there's not much reason for range anxiety. I think some folks that want "more range" when we already have 400 miles would simply want 500 miles next, or 600, so you're hauling around a YUGE battery that goes unused most of the time.
"Higher Range" doesn't mean much. The battery is the most expensive part of the car, and the heaviest. Hauling around a thousand pounds of battery cuts into range and makes the car drive like a tank. But higher range is available RIGHT NOW, just at a price, so your complaint is not really valid. Tesla compensated for this by putting really fast chargers all over the place, and the empty spots on the map pretty much indicate where no one lives anyway.
As to complaining that the map is inaccurate because "you can't drive in a straight line", here again, spend the money and buy what you need. Also, RV parks are everywhere, and you can charge a car there if you need to.
