It's a problem that has begun to affect nearly every state as the nation's average fuel mileage increases. State Senator Tom Wyss (R-Fort Wayne) estimates Indiana's transportation budget could face a deficit in the hundreds of millions in the coming years if nothing is done to change it.
"Just because you've got a hybrid or electric car doesn't mean you're not causing the road damage," says Wyss. In Indiana, as in many other states, the gasoline tax is used to pay for road improvements and infrastructure.
One solution being looked at, Wyss says, is a method that would use GPS monitors to track cars registered in the state, and charge a per-mile fee. Proponents say the method is more fair, spreading the tax burden evenly, regardless of the vehicle you own.
