Well Obama is pushing electric cars like the anemic leaf that Lamar! bought into. The issue is the gas tax pays for road and bridge repair and construction. As cars use less and less gas, states look for ways to get users to pay for the roads they drive on.
Toll roads were pushed for a while. Now it looks like they want to start putting boxes in your car to see where and how much you travel and tax you for milage. I have to say, I thought toll roads was a terrible idea. They look good now by comparison.
