Back of the envelope calculation for the U.S.: Using the national average gas tax of 48¢/gal, if you were to charge an electric vehicle an equivalent of what, say, a 30 mpg vehicle would pay per mile, it'd be 1.5¢/mile, or $150/yr for a vehicle that does 10,000 miles a year. I don't think that's really a huge change to the overall economics either way, though it could push some marginal cases from above to below breakeven.
