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 * (7504) / 2004 ≈ 395

Nearly FOUR HUNDRED TIMES more road damage. Be serious.

@yianiris@ajsadauskas One more important point to share: Overall road deaths per 100,000 people.

The OECD average is 4.28 people killed driving each year per 100,000 people.

The Netherlands is slightly below this at 4.19.

And the USA? It's at 12.84.

Source: https://datahub.roadsafety.gov.au/progress-reporting/international-comparisons

So you are more than three times more likely to be killed on the roads in the USA than in the Netherlands.

And you are more than four times more likely to be killed cycling (per kilometre cycled) in the USA.
