The literature found a range of damage law exponents from 1 to 12
On average, state highways…should consider using a damage law exponent of approximately 2; however, designing for the heaviest commercial vehicles operating on local low-volume roads with a lower life would need to consider a damage law exponent closer to 6.
One consequence is that, even at the lowest exponent, there is absolutely no reason to charge vehicle tax on bikes, if the rationale is to compensate for externalities, rather than just brainlessly punishing cyclists.
Where bicycles typically ride, it is likely a greater discrepancy.
Unsurprisingly, it’s more complicated than that, but…
