For all the faults of the gas tax, like making gas stations be tax collectors for the state, it has been a pretty effective and fair way of apportioning the cost of roads to users. Heavy vehicles that cause more road wear and tear tend to use more gas and thereby pay more in taxes than lighter fuel efficient vehicles. How does pay per mile work when I drive out of state? And how does it collect money from out-of-state vehicles being driven on WA roads? Maybe it would make more sense to just keep the gas tax and develop an alternative taxing method for EVs. But following logic pathways can be so difficult . . .
