You are right. The only way gas tax would be unfair only if you take the position that the drivers of fuel efficient automobiles are somehow getting a "free ride" (pun intended) at the expense their low milage counterparts. But isn't this exactly what the big govt. types have been advocating for years? ie. - create incentives to use less gas? So....if gas taxes really are a fair way to make those who use the roads most pay their fair share, then what is the real reason reason for this legislation? I could accept the "SUV protection act" concept except this is Oregon. They are pretty liberal there and those types generally consider SUV's to be the devil incarnate. From all I've read, those people would love the chance to sock it to the drivers of gas guzzlers and reward the Yugo drivers. I could be cynical and paranoid and believe that the real reason for this proposal is just to give the State the power to be able to track everyone in their automobiles and I'm not sure this isn't the correct answer. This whole thing doesn't really add up and although I try to keep an open mind on things, this doesn't pass the sniff test.
