Transportation is the theme this week, and our special guest is Alex Davies. He edits all of WIRED’s transportation coverage, and he’s the author of this month’s magazine cover story on the Chevy Bolt.

Alex chats with the hosts about what’s up at GM, and how all the automakers getting into car-sharing and autonomous driving. At the end, the crew guesses what sorts of last-mile solutions are going to be clogging the sidewalks and bike lanes of the future. Also: this is Brogan BamBrogan’s mustache.
