In this special bonus episode of San Diego News Now: Chuck Marohn is president of the nonprofit Strong Towns and author of the new book "Confessions of a Recovering Engineer," in which he picks apart everything that he sees wrong with his profession. Too often, he says, streets are designed to accommodate as many cars as possible at the fastest speed possible. Pedestrian and bike safety are often an afterthought. KPBS metro reporter Andrew Bowen spoke with Marohn ahead of his planned talk on Thursday, Nov. 18 at the San Diego History Center in Balboa Park.
