Do they pay fees proportional to the damage they do? I have a feeling that isn't the case, but I could be wrong.
Yeah, even down here in LA almost all the road damage is in the right two lanes where all the trucks drive. In my experience finding a pothole in the left lanes is extremely rare. The high road use fee paid by truckers is absolutely justified. I only question if it should be higher because clearly it isn't enough to even keep up the maintainece of their lanes. The amount of damage done by a Leaf or a Tesla is so minuscule.
