Does the equation not also depend on non-damage-related costs for roads? How much of the total cost of a road arises from resurfacing costs? If a large portion of the costs are unrelated to repairing damage (initial construction, drainage, cabling, signage, traffic management, monitoring, probably a host of others), then it could still make sense to charge cars nearly as much as trucks. I don’t have the data to argue either way.
