How can you seriously claim that roads are not subsidized? With the exception of a few toll roads, there is no fee to use them. Gas taxes are the only tax that can be connected to road use and those only cover about half of the cost of road construction and maintenance. In addition to the subsidy of half of the cost of the roads themselves, there is no tax to cover the cost of the environmental damage that cars cause. Added together, that is an enormous subsidy for car travel.
