Fuel consumption is a great manner for fair taxation for road usage. If the tax isn't adequate to cover the longer range of high mileage vehicles, raise the tax that already exists to double, triple, or whatever seems commensurate to the average increase. Tie it to the US CAFE standards, so that the increase in the CAFE standard will reflect a higher tax revenue as the CAFE standard increases.
