One of the things that I have often wondered was what was going to happen when people shift to alternative fuels to power their vehicles. How is the government going to pay to maintain the roads? At the moment, most of the Federal funding that is devoted to maintaining our road systems comes from revenue from a tax levied on how many gallons of gas you pump into your car. Though this article from the Austin American Statesman only discusses reduced tax revenue due to increased fuel efficiency, those of us who drive electric cars have been getting a hefty break because, well... we don't pump fuel into our cars.
