Walmart uses it a lot more than I do. Civeng principles show that road damage rises to the fourth power of axle weight, a fully loaded tractor-trailer does roughly 10k times structural damage of a passenger car but they definitely don't pay that amount.

And yeah the government is consistently incompetent. But there's no incentive for them to be competent in the first place. Either a mostly exempt-from-competiton company does it badly or a fully exempt-from-competition state does it badly in our system.
