Wisconsin: Higher Taxes For Hybrids, Electrics For Not Burning Enough Gas To Fund Road Repairs?

Green Car Reports

It''s not news that the roads and bridges in many states are falling into disrepair. Much of the money to fund maintenance of this infrastructure comes from taxes on fuel, but that''s something that doesn''t apply to drivers of electric cars--and hybrid drivers pay less than others.
