Hugh Pickens writes "Facing a $10 billion revenue shortfall for transportation financing, the Oregon Legislature is expected to consider a bill to require drivers with a vehicle getting at least 55 miles per gallon of gasoline to pay a per-mile tax after 2015 to offset the loss in tax revenue for fuel efficient cars at the gas pump, where the government has traditionally collected money to build and fix roads. Oregonians currently pay 30 cents per gallon, a tax that is automatically added at the pump, but as cars become more fuel efficient and alternative fuel sources are identified, state officials project gas tax revenue will decline. 'Everybody uses the road, and if some pay and some don't, then that's an unfair situation that's got to be resolved,' says Jim Whitty of the Department of Transportation. Opponents of the Oregon proposal say it will hurt a new industry. 'It will be one more obstacle that the industry and auto dealers will face in convincing consumers to buy these new cars,' says Paul Cosgrove, a lobbyist for the Alliance of Automobile Manufacturers. Other states, such as Nevada and Washington, are also looking at a per-mile charge and a Washington law that would charge electric car owners an annual fee goes into effect in February. Oregon did a pilot study of the mileage tax (PDF) where participants paid 1.56 cents per mile and got a credit for any gasoline tax they paid at the pump. Although initial media portrayals of the system were almost uniformly negative, 91% of test participants preferred the mileage tax to paying gas taxes."
