Suppose you had a 10,000 electric vehicles per day travelling across a 100 mile stretch of Interstate highway. If the average range between charges is 100 miles and average charge time is one hour, there would have to be more than 400 charging stations or an average of four every mile.
This is assuming that power is available 24 hours per day. If solar power was used to generate the electricity it would reduce the time window when charging was available. A more realistic estimate would be twenty chargers per mile, and during the winter travel might become impossible. Throw large semi trucks into the mix, and it becomes a completely unmanageable mess. No one would get anywhere.
