Uber filed to go public this week. No big surprise there; everyone in the industry has been waiting months for the ride-hailing giant to hit the accelerator on its IPO. What did raise an eyebrow were the details the company divulged in its filing—from how it views the future of its business to what it considers its primary challenges in the marketplace.

This week, we invite WIRED transportation reporter Aarian Marshall back onto the show to break down all of the revelations in Uber’s S1 filing. You can read her news story about the upcoming Uber IPO right here on WIRED.
