More people own cars in the US -> more gas purchased -> more total tax. Contrary to popular belief, the amount of cars driving over a road doesn't really contribute to how often it has to be repaved/repaired -- a road's wear is almost entirely based on its age. The more cars you have, the less fuel taxes will be to maintain the same amount of road surface. This means that when EVs become more popular, there'll be clever ways of taxing them too, whether it's an insurance surcharge or an up-front purchase tax or some sort of special "electricity for EVs" tax. This is the honeymoon period when they seem super cheap to drive, but that'll change as they replace fuel-powered cars and someone needs to pay for the roads/infra.
