Most American communities don’t even bother to count what percentage of the population can't legally drive. In the handful of states that have tried, though, the answer has been around 30 percent – which is just enough to create a real movement for change, if we'd all just band together  On today’s episode of The Brake, we're bringing you an extended audio version of our conversation with author Anna Zivarts, who has been quietly building that movement of non-drivers through her work with groups like Disability Rights Washington and America Walks. And in her new book, "When Driving is Not an Option: Steering Away From Car Dependency," Anna outlines what you can do right now to to center the needs of people who are the least well-served by our auto-dominated transportaiton system — and how that shift would benefit even those who are able and willing to spend much of their lives behind the wheel.
