In the Great Depression, NC state government took over building roads that had previously been a county responsibility, and it may be that such expenses here are simply to a greater degree at the state than local level.
I doubt there is a great deal of difference in road upkeep and construction cost between Georgia (29.1 cpg), Virginia (26.2 cpg), S. Carolina (26.75 cpg), and NC at nearly 39 cents per gallon, plus the federal rate of 18.4 cents a gallon. NC is simply gouging fuel users more deeply than surrounding states.
As one who pays $75 annual 'hybrid fuel tax' every year our car is registered PLUS road tax at the pump, I take offense at the premise that I'm somehow getting a 'free ride' or not paying my share.
But as one who does so, I'm a helluva lot more 'tax wise' than someone who defiantly puts airplane gas in a car and pays the taxes for both!
Carolinian, when I came to TUG, I took many of your views as 'gospel'. As one who admired your work in Eastern Europe, I somehow thought you were doing good by helping others, but now, I see your views as misguided, and not fully thought through.
I wish you well, but feel that you are trapped in a world of some 40odd (or more) years ago. Obviously you are comfortable there, but proselytize as you will, that world has moved on. . . . Adieu.
