My impression is the opposite, so in the absence of harder evidence we're at an impasse. But even if Google Maps isn't widely used, Google could trivially spend the cash to market the feature if it wished to, or hell, just pop up an alert upon opening the Lyft or Uber app on Android that says "Did you know that you can compare ride-sharing prices across all services in your area via Google Maps? Click here to try it!" (in the same way that visiting any Google property on a non-Google browser pesters the user into downloading Chrome). Google already owns the platform, Google already owns the maps data, Google already owns the users.
That’s a compelling reason to use non-Google apps. Don’t they have enough hooks in my data already? I still think you might be right ultimately since most people prioritize price and convenience over their long term best interests.
