Actually, for us Westerners, the route that is being assembled through Arizona, New Mexico, Utah and Colorado is a very highly traveled route. It is a wonderful vacation route that I travel at least once if not twice a year. It is by far the better scenic route from coast to coast, and it adds only a few miles over the most direct, boring route. I am very pleased as are a number of my friends, all of us very much in our "right minds".
The California to Las Vegas, Flagstaff, and Phoenix Supercharger deployment is totally reasonable.
Flagstaff to Denver is ridiculous, and manages to get you neither to Albuquerque nor to Salt Lake City. It's not *practical*, it's just Elon's personal road trip.
Chicago to South Dakota is reasonable for what it is, but it doesn't really get you Chicago to Denver or anything likely to be used by most people.
Cheyenne is OK for people heading north from Denver to anywhere...
But Wyoming is the lowest-population state in the country, and the chances of anyone in their right mind driving through Wyoming from Denver to South Dakota... well, you'd only do it if you were *specifically* going to Mt. Rushmore.
So, basically, the "coast to coast" deployment is based on one man's quixotic road trip, and to hell with anyone trying to make any other trips. It is what it is -- being CEO has its privileges.
And I wouldn't complain, except that they advertised an entirely different deployment schedule which they've now abandoned.
