There might be no greater proof of how unsustainable our urban planning has become than the commute times into and out of America's major cities. In short, if you gripe about spending 30 minutes in your car every morning, consider yourself lucky: Angelenos, on average, spend 70 hours a year stuck in traffic. And that's just delays -- we're not even talking about commute times. Austin residents, meanwhile, have a relatively sane 34 hours of delays a year--but they spend almost $350 (?!) a month on gas.
