Quick quiz: What city is the world leader in highway teardowns? San Francisco? Portland? Madrid?

Wrong, wrong, wrong. It's Seoul, South Korea, which has removed 15 urban highways -- and is about to remove another. In this week's Talking Headways episode, Jeff and I talk about what can take the place of a freeway in a city and why it's worth it.

We also debunk the argument, made in Atlantic Cities and the Washington Post last week, that promoting car access will benefit people with low incomes. The whole concept is based on a study that basically said that in the 90s you needed a car to get around the suburbs. Not exactly a persuasive justification for automobile subsidies in today's cities.

We wander down Saffron Avenue and Nutmeg Lane to investigate whether it's true that cities are losing their smell -- and whether that's really such a bad thing. Then we accidentally trip into a conversation about pheromones and good-smelling men.

What's your favorite smell in your city? Let us know in the comments.

We're working on getting the podcast available on Stitcher, which apparently is a thing that exists, but for now you can subscribe on iTunes or follow the RSS feed.
