The truly walkable city seems like something only small European cities can obtain, but urban planners have grand plans. Natalie Whittle is a contributor to the Financial Times, and she joins host Krys Boyd to discuss the idea of the 15-minute city, where cars aren’t necessary, bikes abound, and all amenities are a short walk away. Her book is “Shrink the City: The 15-Minute Urban Experiment and the Cities of the Future.”
