Why are America’s streets so dangerous — and what can we do about it? In this episode, Chuck talks with Wes Marshall, author of “Killed by a Traffic Engineer” and professor of Civil Engineering at the University of Colorado Denver. From the history of traffic engineering to the failures of Vision Zero, they explore how design decisions shape safety — and what it will take to build streets that protect everyone.
