Hmmm, brings up something to ponder. Most of the taxes on gas go to pay for road construction & maintenance. Electric cars don't pay that tax. At some point in the future the quantity of electric cars on the road will grow and the tax revenue from gas sales will decrease, yet roads still need to be built and maintained. I foresee some sort of tax on electricity when used to power electric cars, or some sort of yearly tax based on mileage for each electric car - maybe assessed when you get your yearly inspection? Nobody like taxes, but they are important to pay for common use things like roads.
1. EVs pay tolls like everyone else (except in certain states). Here in Texas the plan appears to be to turn every highway into a toll road--and a very expensive toll road at that.
2. EVs don't have messy oil spills and leaks that costs states many millions to clean up.
3. As the EV population increases, healthcare costs will go down due to a cleaner environment.
4. Big rigs do most of the road damage and don't pay nearly their share.
5. Roads are often constructed cheaply and so are subject to frost heaves and ground subsidence.
