A transcript of my podcast with Jim Pethokoukis is now up: The end of traffic in America: A Q&A with transportation expert David Levinson.

By the year 2030, most Americans may only head into the office a few days a week, lots of urban skyscrapers will have been converted into apartments, suburban land prices will have declined, and we’ll be “driving” — or at least sitting in autonomous cars — way less. Goodbye to traffic congestion.

That’s a bit of the possible future sketched out in a recent blog post – “What happened to traffic?”– by transportation expert David Levinson of the University of Minnesota and author of the Transportationist blog. I chatted with Prof. Levinson about his fascinating speculation for my Ricochet Money & Politics podcast.
