I think he is close though with his initial train of thought. I remember doing some research on this many years ago and road wear does not scale linearly with weight. All other variables being equal a 1,000lb load going across a stretch of road 10 times does less damage than a 10,000 pounds load going across the same stretch once. So what we should really be doing is looking at semi trucks and the heaviest of consumer vehicles. It would theoretically make consumer goods go up in price a little, but it’s not like that cost isn’t already being paid/subsidized by consumers in other ways.

Maybe it would even push the use of railroads for goods even more than it is used now.
