I never actually open the maps app on my iPhone. I just ask Siri for directions, and I presume she uses the default Apple maps as the base. I'd suggest that the data is skewed because a lot of people would be doing the same thing. The evolution of the phone UI basically indicates that individual apps are fading as identifiable components. Modern bots and mashup interfaces just pull data from different app/sources and present an amalgamated view. I neither know, nor care whether Siri is pulling her route data from Google or Apple maps, or somewhere else.
