Do U.S. automakers have any new ideas about how to make congested, polluted cities more accessible? Can they think beyond 1.8 cars per household?

David Berdish of Ford insists they can. David is developing sustainable mobility solutions for the world's mega-cities. David is Manager of Social Responsibility and Organizational Learning at Ford where he has worked for 24 years in the areas of Production, Program Management, Finance, Quality, Business Planning and Organizational Learning.

Also with us is Marsha Miro, acting director of the Museum of Contemporary Art Detroit, which is opening a new exhibition this month about shrinking cities worldwide. Marsha previously taught art history at the Center for Creative Studies in Detroit and has numerous books and a film on Cranbrook to her credit.

We'll talk about the challenges cities face in moving people and managing population shrinkage this week on Smart City.
