I would support higher taxes for lower mpg vehicles.....it has to go that way...it is totally fair, IMV.
High gas prices are the best thing that could happen, painful as it is. It has changed how my family lives, because it finally pinched. The pain must correlate to the usage---reality. We still have big rigs, but we drive them about half as much. if we had smaller cars, we could drive more.--this forces people to choose, up against the brick wall of reality.
Our love for nature and fish will not stop us from driving somewhere. The need to buy groceries and medical care will.
