Not many people like to think about traffic but Joanna Oda says this very topic on IDEAS in 2005 permanently changed the way she views medical care as a doctor. "It helped me understand how things that make sense for you as an individual contribute to a collective problem." She adds, the episode introduced her to the idea that one car has a big impact.

This episode is part of a week-long celebration to mark our 60th anniversary. IDEAS is giving the mic to listeners like Oda to share their stories on how our program led to life-altering moments.
