So, if all of our roadways will be paid for by tolls, when do the gas and registration taxes get rolled back?
Surely you jest...and I know...don't call you Shirley.
The gas tax that you pay will continue to be used as it is being used now. It will definately be raised because there will be new roads built, the existing roads will get older, and there will be more cars using them, meaning higher maintanance costs. Additionally, as cars get better and better milage, the gas tax collected shrinks.
