Countless communities across America say they're planning for a future where more residents walk, bike, and roll to get around. So why do transportation leaders spend so much time drafting "pedestrian master plans" and "bike master plans" without accompanying "car master plans" aimed at building a world where fewer people get behind the wheel?

Today on The Brake, we're joined by urban planner, community organizer and all around rad person Cathy Tuttle, who actually sat down and wrote a car master plan for her own city of Portland, Oregon. And she hopes that advocates and transportation leaders in other communities will follow her lead — because if they don't, she argues, we'll never truly reckon with the impact of car dependency on our communities, much less chart an effective strategy to dismantle it.
