A few years ago, Melissa and Chris Bruntlett and their two children moved from Vancouver, Canada, to Delft, a small city in the Netherlands where 80% of journeys are taken by foot, bicycle, or public transit. Their new book, Curbing Traffic: The Human Case for Fewer Cars in Our Lives, is about what it's like to live in a truly low-car city, and how other cities can capture some of the same benefits.

Reading the book was a joy for me -- it reinforced so many of my priors! -- so I was excited to talk to Melissa and Chris about how to design streets for people, the connection between urban infrastructure and social trust, the flourishing that Dutch children enjoy, and the myriad evils of cars.
