It is true that as higher-mileage cars and EVs replace today’s vehicles, the revenue from gas taxes will go down, which could reduce the funding that’s available for building and maintaining roads. States can replace the lost revenue by charging EV owners an extra fee when they renew their license plates—19 states are doing this as I write this chapter—though it means it’ll take a year or two longer for EVs to be as cheap as gas-fueled cars.
This is an example of what NOT to do. EVs having advantages (such as no gas taxes paid since they use no gas) is an example of a mechanism we need to get more people to change to EVs.
