I'm sitting here wishing that the Uber app had an audible surge notification (that goes off if you are within the surge area). I wish for this because when I take a break, I'll sit and read a book or something. Or close my eyes to rest them. And when I do, it would be great if the app had the feature where it would "chime" if a surge occurs when you are within the surge circumference (discovered by the phone location). Then I would decide that "breaks over" and hit the blue "GO" button.
