The issue of fuel taxes as road taxes should be resolved, and should have been resolved ahead of time, so that to the extent that fuel taxes are appropriate, all vehicles, “fossil fuel” powered or otherwise pay some form of them; some form that amounts to an equal assesssment of “fuel” consumed.
Leaving “fossil fuel” vehicles alone paying them IS an injustice, amounting to a lack of “equal protection” of the laws, as all vehicles, including “alternative” vehicles use the same roads.
When you return to my first statement, you realize that the author is correct in one thing. Not only WILL electric vehciles be assessed some “energy/fuel” tax at some point (in my opinion they should be in equality with fossil fuel vehicles), but also, if they are as energy efficient as the author suggests (in terms of the per mile amount of energy consumed), then should electric vehicles ever dominate the road either their energy taxes will be raised a lot, or the politicians will find some other way to assess everyone for taxes to support the roads.
If the author was right on the cost / benifit of electric cars they would domintate the market. And here are reasons why

Oh and no one will pay the cost for one with out .Gov s subsidy $7500
When/If supercap or hydraulic / mechanical hybrids become available they will be a better solution then LiOn is right now I think.
