You're not taking into account the fact that rail transit is primarily in cities, where costs are high. You can't compare cost per passenger-mile for roads in upstate NY and subways in Manhattan. > Roads are cheap and not heavily subsidized when you account for how many people use them. [citation needed]. You haven't said that fraction of road costs are covered by subsidies (e.g., by property taxes). I suspect it's a substantial fraction.
