Yes.
HOWEVER
between me and the wife, we drive about 65,000 miles a year
(seriously, we do), but we cause LESS road wear, than a 40-ton HGV
that drives 500 miles

I am trying to remember my source, but I believe that a fully loaded
40-45ton truck does the same wear damage to the road, as 1,000
passenger cars. (Using US gallons)we get ~ 25mpg roughly, while a HGV
here gets maybe 6.5mpg (new frieghtliner cascadia). He uses fuel 5x
faster than I, but damages 1000x faster.

Wear from just 'cars' on a standard road surface is negligible.

This is why the fuel tax usage is a bit off.
