I saw on another topic that Mercedes goal was to have its entire line of cars non petroleum fuel based. That combined with the resurgence of electric and hybrid vehicles and the EPA CAFE regulations that demand higher mileage cars begs the question.....
How will we pay for roads when gas tax revenue falls? As it stands now, auto mfgs are beholden to the internal combustion engine because it will take loads of engineering dollars to change to a different power source that they will have a hard time recovering. Oil companies don't want to change their fuel delivery infrastructure. The government also has a vested interest in keeping the current system as it is how we fund road construction and maintenance.
If you have a plug in electric vehicle, how do you pay for your share of the road maintenance and construction?
Should you pay a mileage fee at the DMV when you register it? This means that those who drive more would pay more since they are using more.
Should you pay a fixed "electric vehicle use fee" annually when you register it?
Should we start transferring over to toll roads?
Should you pay the electric company a tax? What if you generate your own via solar or wind?
Obviously hydrogen and biofuels can be taxed at a delivery point, so that could be set up as a similar system.
Should you pay for what goes out the tailpipe too?
Interesting questions that surely will need to be answered. Things to keep on top of before your legislator makes up your mind for you!
