I think ALL public transportation including cars are subsidized in most countries. I know that mass transit in Europe and in the US is heavily subsidized. There is no way it could subsist on just the fares. Ditto cars, we all pay taxes to build local roads and interstates whether we utilize them or not. As well as all the tax breaks and subsidies that the oil companies and auto manufacturers receive. Eventually it will have to come down to what is going to give you the most for your subsidy dollar.
