If the coverage area of anything is 95% and one does not live in the nearly complete and widespread coverage area, then one is in the vast vast vast minority. Such is the cause of the statement...."in the middle of nowhere"...
If something covers 90 percent of the lower 48, it would have more than one of itself in Iowa. According to the map there are 4 or 5 along the I-70 corridor that stretches from St. Louis to Kansas City, but none along the I-80 corridor between Des Moines and Chicago.
A bootless argument, anyway. Just for grins, I went and looked at the Tesla S website. I'm in the market for a car, and thought I'd see what I could do.
According to that website, the shortest-range S, the 65kw model, sells for $71,070, and has a monthly payment of $916 (for people who qualify for the 2.95 percent interest rate and 72-month financing). The estimated actual monthly cost of ownership, due rebates, fuel savings, etc., is $579.
Although it would be tough for me, I could swing a car payment in the $579 range -- but that wouldn't be my payment. That would be my "ownership cost." And I'd still have to have another car for the long trips I make once or twice each month -- and that would be true in 2015 when there is 95 percent charger saturation, too.
Tesla/Musk have great marketers and build what appears to be a great car. To be truly great, however, they're going to have to halve its price and double its range.
