Active transportation advocates constantly get accused of waging a "war on cars." But when you look around our communities, it sure looks more like we're in the middle of a war on walking and biking — and the wrong side is winning. In today's episode of The Brake, we sat down with Dr. Tepi McLaughlin, who co-authored of a provocative new paper that argues it's time to name the "enemies of physical activity" and dismantle policies they push, rather than just focusing on the additive benefits of building more sidewalks and bike lanes. And along the way, we talk about some of the hidden ways that corporations and policymakers have made non-automotive transportation so dangerous and rare, and what we can do to change it.
