Well my personal opinion is these larger vehicles should require a special license to drive. And once we kill gasoline and diesel on our roads, we should tax based on 1) wear and tear on the roads and 2) risk to pedestrians and other vehicles. Weight is an okay stand-in for that metric, but isn't perfect (there are ways to distribute load on the road using the wheels that reduce wear, and there are design features like a low hood or even external airbags that could be used to reduce fatalities to pedestrians and other vehicles). But we shouldn't go there until we've all but eliminated fossil fuels from our roads.
