> 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.
