Something I find interesting about this is that it weakens the notion of the app being a relatively pure marketplace connecting a driver to a rider. The more that these features emerge, the more complex the relationships, and the more prominent the role of Lyft/Uber/Sidecar as more than a "mere" broker.

I wonder how much we're going to see things go full circle, and have a more employee-like relationship between drivers and these services (see also the "guaranteed wage" that these services have been offering to some drivers at peak hours).
