*Oppose - The term "VMT" is directly related to the legal position for the specific jurisdiction. It may or may not be a tax, and certainly in the most advanced example of this (Oregon) it IS a tax, and is explicitly said to be so by those responsible for it.  Overall, it is worth noting that distance based road charging (which is what this has been called in the past and in other countries) has been around for decades.  Four US states still have it for trucks, and given the five countries that have it don't call it this, then debate about nomenclature may be better subsumed into the introduction by called it VMT, distance based road user charging, time/distance/place based charging, distance based tolls and mileage based usage fees.
