37mpg is still way too high for anything other than a sewing machine. 57mpg means driving all electric, with no infrastructure to support it.
I saw electric charging stations at the Delaware Turnpike (I-95) service plaza on the way back from seeing a friend in Pennsylvania. I believe, however, that the service plaza IS a state-owned facility being run by a private company.
How many charging areas will pop up entirely in the hands of private enterprise, without subsidy, I have no idea.
