Cities are ripe with sharing opportunities. That's kind of the point of cities, when you think about it. Shared infrastructure, culture, and space are what make cities dynamos of the global economy. And when citizens and governments plan a city together, an even more shareable city is possible. Increased innovation, resilience, and prosperity can follow. That's what Park Won-soon, mayor of Seoul, South Korea, is banking on with his ambitious "Sharing City" initiative.
