In the US gas taxes are very low and don't even cover the costs of our highways. Local roads are paid for mostly with local taxes. It's hard to quantify exactly the subsidy per passenger mile while driving, whereas it's very easy to do the same for transit. The system we have makes drivers feel as though they are paying their fair share while transit riders are not. They don't see the share of their local taxes going to roads.
