Germany already has a toll system installed for trucks on its autobahns, the politicians are just biding their time and waiting for when they will be able to expand the sytem to include all vehicles.
It is all technically possible, although a tax on gasoline per gallon favors lower fuel consumption rather than a fee per mile driven.
In the Netherlands you are charged a yearly road tax and it is rated on what kind of car or truck you are driving..Last I remember my buddy over there drives an SUV and pays 150/Euro a year plus expensive gas.
