Think of how often dedicated walking and cycling routes need to be repaved—almost never.
Car owners only pay about half of the cost of road maintenance in the US[1].
> The degradation of road surfaces is caused almost entirely by automobiles.
Given the fourth power law I find it hard to believe that larger vehicles, especially good vehicles , are not significant.
Even without wear, surfaces deteriorate. You cannot claim that pavements and cycle lanes are zero maintenance, or have negligible costs to build.
This should read: The degradation of road surfaces is caused almost entirely by heavy trucks.
Road wear is proportional to the fourth power of axle weight. A fully loaded cement truck or transport truck is doing way more damage than a fully loaded box truck, which is doing much more damage than a Hummer EV, which is doing much more damage than a Tesla Model S or F150, which is doing more damage than a Nissan Micra or Mazda Miata. Here’s[0] a page with a neat chart showing relative comparisons. Note that it tops out at 18k lb trucks, which are ~1200x as damaging as something like a Prius; it doesn’t include fully loaded trucks, which can exceed 80k lbs in North America. The amount of damage to roads they do compared to average or lightweight cars is mind boggling.

The condition of many german cycling paths would beg to differ.
