Is it though? Is it critical to cover ever area?
YES.
Eventually yes but for now?
YES, RIGHT NOW.
I live in the wealthy/dense suburbs of Kansas City and my nearest SC is an 45minutes to an hour away. I guarantee it will get more use than some random road in North Dakota.
The point of Superchargers is
to make road trips possible. For that you require
geographic coverage.
Tesla actually
wants low usage. High usage is expensive and unnecessary for Tesla. In bigger cities, there will alreay be other places to charge (at home... at your hotel...) and Tesla wants to drive as many people as possible to those locations. (Pricing should be below gasoline, but above all possible destination chargers).
Making road trips possible
sells cars which will otherwise not be sold. Right now, I literally cannot drive to visit my friend in North Dakota. It is an incredible marketing failure.
This is not the biggest issue from a marketing perspective -- that's the service issue -- but it is the one which can be fixed by spending under $20 million dollars. It's penny-wise, pound-foolish to not finish the US geographic coverage, especially when they're *so close*. Being able to advertise "Drive anywhere in the lower 48 states, knowing that there's always a place to charge" is incredibly valuable.
They can't say that right now because of North Dakota.
Now, in Mexico, for instance, Tesla is a lot further from geographic coverage... so maybe it makes sense to postpone Mexico for a while. Same with Australia. But there's so little money needed to
finish the job and have a massive selling point in the US, that they really should finish it.
It's like
almost finishing a building and then just sort of leaving it there because you can't be bothered to spend money on the last few punchlist items. It's really weird.
