- underdeserver 3y agoThis is interesting! If I understand it correctly, it means that damage to roads is completely dominated by trucks, as long as you have more than 10,000 cars per truck. Near my home I would estimate it at around 100 cars for every truck. This means that cars are completely negligible, and that supporting road construction and repair by taxes (ideally, direct taxes on the truck users, which is then rolled on to consumers through higher prices) is correct.
- pfdietz 3y agoCars add cost by requiring the roads to be very smooth. A large truck might be fine with an unpaved road. Places like mines or forests with large traffic of heavy vehicles don't typically pave their roads, I think.
