A tidbit from an interesting (read: transit-friendly) article in Slate:

You think the government is wasting a few billion a year on mass-transit subsidies. But what about the huge subsidies for cars and trucks?

[…]

What hasn’t been acknowledged is that the automobile is supported by a government subsidy that dwarfs anything provided to mass transit. How big is the subsidy? By my (admittedly extremely crude) calculations, it could total nearly $100 billion per year.

Can I get an amen?

There’s more to it, of course–but that’s what the link is for.
