This exactly. I think eventually we could see a Kayak-like service that just compares rates for your trip against a set and books accordingly. Containing Uber/Lyft/local taxi service/etc. It's very easy to enter the market. You just need a map in a UI (mapbox) and a way to charge people (stripe/square). There's probably a decent market for transportation-service-as-a-service. $1000 gets you all setup with a custom app (configured instance of a general app).
Drivers could have something similar where they see all the opportunities and potential fares across platforms in one app. What do they need? A list box to select the fare, then a map with reasonable routing, and a pay processor.
