Not aware of any state or the federal government which has adopted gasoline taxes specifically intended to at least maintain the revenue base when and if electric cars/hybrids become more popular......., but its only a manner of time. As an example, I believe CT gas tax or a portion of goes to the General Fund rather than specifically for the Dept of Transportation.

How will an all electric vehicle be taxed on usage, not sales/property tax, in lieu of not purchasing gas. How will the mileage usage be monitored ? Will be another Health Care issue.
