originally we were taxed by a price per gallon, and then the politicians saw a opportunity to profit and profit big. They started taxing by a percentage of cost. Remember the killing they made last summer at $4+ a gallon? I do!
I guess if they try to put gps in my vehicle I would just have to tamper with it, or attach it to a car that is not being used much, like my summertime ride.
They dug their own hole by raising prices last year, and then destroing the economy. Then when we cut back our driving and others drive like my grandmother with bad eyesight, their revenues dropped. DUH!!

Deal with it! I feel no sympathy.
