Okay, so we're getting to the bottom of this. It definitely came from the U.S. Chamber of Commerce, which is not some wacko right wing radio pundit, but does generally promote a pro-business conservative agenda.
The study was published on November 3. So it took some time to produce any ripples.
Here is the whole executive summary -

Here is the pertinent section -
"Midterm Strategies: 2010 to 2015
By 2010, the federal government can begin to broaden the base of
user payments to the HTF by collecting a vehicle fee to capture
fair payments from auto and truck users regardless of the type of
fuel used.
To ensure adequate federal transportation revenues beyond 2015, the
federal government can supplement current federal motor fuel taxes with
an annual federal vehicle tax on hybrid and nonpetroleum-powered
vehicles so that all passenger vehicles pay their fair share of highway use
costs. If the federal government wishes to subsidize the purchase of
hybrid and nonpetroleum-powered vehicles to reduce fuel consumption
and emissions, the subsidies should be provided from the general fund,
as was done for ethanol fuel subsidies, and not from the HTF.
The tax rates for hybrid and nonpetroleum-powered vehicles should be
determined by a new federal highway and transit cost allocation study.
Cost allocation studies have been used since the 1956 Highway Act to
determine the appropriate allocation of federal fees, whether based on
fuel consumption, vehicle type, or mileage. This was the approach used
to set federal vehicle taxes for heavy trucks. Diesel fuel taxes alone do
not cover the highway costs occasioned by heavy trucks. To ensure
that trucks pay a fair share of the costs of building and maintaining
highways, diesel fuel taxes are supplemented with the Heavy Vehicle
Use Tax (HVUT), an excise sales tax on heavy vehicles, and tire taxes
paid into the HTF.
The recently authorized National Surface Transportation Infrastructure
Financing Commission can oversee the new cost allocation study,
setting principles and guidelines for the efficient and equitable
allocation of HTF fees."
That doesn't sound too extreme to me. And it certainly isn't going to happen any time soon.
