As repairing roads costs so much, it annoys me that we don't make some attempt at penalising the heaviest vehicles. As road damage is roughly proportional to the fourth power of weight, it would make a lot of sense to prevent logistics companies from just using the largest vehicles that they can - it should work out costing less if loads are broken up and delivered via multiple, lighter vehicles. However, as the public bears the cost, it means that logistics companies will just look at their expenses (drivers' wages, fuel etc).
