Uber is currently testing out something called “Smart Routes” in San Francisco.
Basically it works similar to UberPOOL (where you carpool with strangers to bring the cost down), except that your pickup location (and trip?) is confined to a specific route.
This means less detours and more rides for drivers, as well as even cheaper fares for passengers. But just like public transit, you’ll likely have to walk a few minutes to get to the closest route.
Here’s a screenshot of what that looks like (via TechCrunch):
