Susan Carpenter is co-host of The Ride, a series about modern mobility on the Southern California Public Radio Station, KPCC-FM. In broadcast radio segments and a weekly podcast, she reports on everything from autonomous cars and ride sharing to motorcycles, bicycles and public transit. In 2004, Carpenter wrote a book about her experiences as a pirate radio operator which has been described as "sine qua non for anyone who aspires to run any kind of community-style radio station" due to the details it provides about the college/community/pirate scene.
