I love this chart. The simple truth is that road wear isn't caused equally by all road users, and it isn't even a linear relationship to vehicle mass.

It's GEOMETRIC.

Estimates of road wear use the FOURTH power of axle load.

Me + my bike, fully loaded: 200Kg
Toyota RAV4, dry mass: 1500Kg, 2 axles
2 * (750**4) / 200**4 ≈ 395

Nearly FOUR HUNDRED TIMES more road damage. Be serious.
