That was one introduction to this story, here's another. Back when I was a sophomore in college I took a philosophy class which we cadets nicknamed "drugs". In that class I learned about Kant's Moral Imperative: what would be the result if everyone took the action you were considering taking? If you wanted to lie, for example, what would the result if everyone were lying? Obviously not good, don't do it.
Those two lead-ins bring me to this story. What would happen if everyone drove a hybrid, or at least if they got good mileage and didn't use as much gas? Why, gas tax revenue would decline! Yet (in theory) we want all the things from government that that revenue pays for, so what to do?
Oregon is moving ahead with a controversial plan to tax motorists based on the number of miles they drive as opposed to the amount of fuel they consume, raising myriad concerns about cost and privacy. The program, springing out of a recently signed bill, is expected to launch in 2015 on a volunteer basis.
But it’s charting relatively new territory, and other states aching for additional tax revenue are sure to be watching closely to see whether to imitate the model.
