It's going to be a wild ride. While (*most) people seem to like using Uber, headlines about how the unit economics don't work, how drivers can't make a living, how their working conditions aren't tenable keep popping up. How does Uber intend to address this?<p>In addition, I have questions about the service's ability to grow significant multipliers. It really feels like they've reached the majority of their markets three years ago, and have been tweaking things since. Why would you invest in this? Is there a clear value proposition for future growth?
