    Heavy vehicles are the only thing that can put any meaningful wear on roads and streets, due to the https://en.wikipedia.org/wiki/Fourth_power_law that says that the wear on the road is a function of the fourth power of the mass of the vehicle over the number of axles. A car puts 160,000 times as much wear on a road as a bike does, and the step up to heavy transportation vehicles involves a similarly massive jump. Every time a heavy truck moves a shipment over our roads, there is a real cost that we have to pay in maintenance that has no equivalent for personal vehicles.
