By itself, there are no network effects, but they're offering special deals that do depend on network effects. For example, the carpooling services[1] scale disproportionately to the number of users, because that increases the probability you can find people on similar start/endpoints to split the ride with.
Ditto for bill-splitting functionality for the rides, where you care about whether the other person uses the service.
What I want to know is, how long until someone writes a wrapper around all these services so you have a one-stop deal for selecting from all of them?
[1] UberPool and Lyft Lines, and now Lyft hotspots, which ingeniously tries to concentrate people at nodes, which makes carpooling aggregations trivial.
