> Expect this to increase as people become more used to hailing cars from inside of their maps applications which act as aggregators.

I feel like the prices I get from within Google Maps are both vague and higher than the prices I get from opening the actual apps, so I never actually use the Google Maps integration and just end up checking both apps, which is pretty annoying.

I think the Maps integration is basically a customer acquisition tactic, not something they expect most people to actually use.
