The Federal gas tax hasn't been raised since 1993, so because of inflation, it's not enough to cover road maintenance. In most states, it covers less than 50% of costs, in many states it's less than 1/3, and in Alaska it covers only 6.9%:
https://taxfoundation.org/states-road-funding-2019/ So the truth is that cars, gas or electric, don't really pay for road maintenance. In states where they've implemented special EV fees, EVs are probably paying even more than gas cars for road maintenance.
The fairest way to fix this problem is to implement a per mile fee that's adjusted for the weight of the vehicle. Most of the damage is probably done by trucks hauling cargo, but can you imagine how politically unpopular it would be to tell big corporations that their trucks need to pay their fair share of road maintenance? And that's how the rest of us gets stuck with their tax bill. The notion of EVs not paying for road maintenance, while having an ounce of truth, is really a huge distraction from the real root cause of the issue.
