I do agree the relationship probably isn't linear, but the fourth power rule doesn't necessarily have numerous studies confirming it. It was a small collection of studies on road wear the US highway administration did in the 1950s and pretty much everyone has just gone with that. Other studies have pointed to it being less than previously thought.
Thanks for the insight but my claim was never "12,000mi is really 35,000mi"
Regardless, it would be interesting to see the actual number worked through to see what the equivalent EV registration fee should be if road damage/maintenance is the sole factor.

You absolutely did suggest me paying taxes for 12k miles is practically the same as ~35k miles, you said it several times. That it's not far off. How else am I supposed to read that? You were so sure of it you mentioned it many times.
> Regardless, it would be interesting to see the actual number worked through to see what the equivalent EV registration fee should be if road damage/maintenance is the sole factor.
Sure, but it's likely far less than what I'm paying. As mentioned elsewhere, a similar weight unloaded F-150 pays half the taxes. So I'm at least paying double for similar weight vehicles, and yet you tell me it's really only 6%. But sure, tell me again how I'm really just paying my fair share and 12 = 35.
> If that's true, then 12-15k miles in an EV would be equivalent to 27-33k miles in a gas car in the externalities of road wear & tear.. so "taxes equivalent to 35k miles" is at most 25% higher in a "damage per mile equivalent" but could be as little as 6% using the averages.
^ As you quoted, I used the formula to estimate 12k would be equivalent to 27k and said paying taxes equivalent to be 35k miles is "at most 25% higher", neither of which is "12 = 35". Using their approach, I calculated 35k to be equivalent to 15625 specifically, again, not 12k.
If the underlying approach is wrong, we should replace it with something better.
Alternatively, the OTHER reasoning of "the rich should pay more" still applies, so I assume that's a factor here. Hoping States charge rich people (or high income earners, if you prefer) less isn't likely to work right now.

Once again, your assumption is incorrect. That base model F-150 that pays half the taxes costs more than my EV. The registration fee doesn't factor in income or valuation at all. A $100k Hummer EV pays the same as a $15k used Bolt. Meanwhile that Hummer EV is going to do a hell of a lot more damage to the roads than the Bolt.
It probably has more to do with the government being in the pocket of oil interests and acts accordingly.
