This is true, but it's also changing in interesting ways: the rise of both light-truck SUVs and EVs as a whole means that passenger cars are, on average, heaver than they've ever been before.

This is still a small portion of overall road damage, but it matters in places like NYC. In particular it matters on our bridges and cantilevered highways, where passenger traffic can't be easily filtered away from weight-sensitive areas like commercial traffic can.
