As more and more EVs hit the roads, paying for the highway infrastructure based on fuel taxes will become way lopsided. Expect everyone to eventually end up paying a per distance tax and the fuel taxes at the pump may go away. The administration of that could be messy, but I think it will happen, maybe sooner rather than later in some markets.
