Google has had the ability to show price estimates and pickup wait times for ride-sharing apps for a while. Back in January 2017, Uber alone gained the ability to actually book rides in the Google Maps app by pulling up your account window and hailing your ride without ever leaving the app.
But for whatever reason, Google has officially removed the feature from the Android app, demoting Uber back to the same level as the other ride-sharing apps it supports, like Lyft and Gett. You’ll still be able to see the estimated cost of different Uber rides in Maps, but you’ll now have to go to the actual Uber app to finish the booking process.
It’s not entirely clear why Google is removing the feature. For what it’s worth, Alphabet’s venture capital business has made a large investment in Lyft. But the Google Maps help page regarding the function has been updated to explicitly note that “you can no longer book Uber rides directly in Google Maps. But you can still look up the route in the Maps app and then request the ride from the Uber app.” That applies to both the iOS and Android versions of the app, so it appears that this feature is gone for good.
