Mary Peters sure seems to be against raising the gas-tax, even though many have recommended it. There's no way 18 cents is doing the same as it was back in 1993, when the tax was set. I really think this gas-tax holiday will seriously hurt us in the long run. So are we slowly going to get away from rail vs. highways and go toward rail AND highways? I sure hope so, but I don't think private firms charging tolls will help reduce oil dependance nor will it help the argument for more mass-transit and intercity rail. OTOH, I'm not totally against tolling new roads either. I have no data to back myself up, but it SEEMS to me that the toll roads I sometimes drive on, there is less urban sprawl. People won't drive on it as much because its harder to drive on for a short distance, therefore there is less strip mall development near exits. I know thats not totally true, but in some rural areas where a toll road is, it seems to be the case. So with that said, I just think the simple solution is to raise the gas-tax, even if its a few cents.
