Not sure if this is helpful or not but that kind of thing never matters to Google. They just build it. Residents of four American and two European cities can now get live updates on when the bus or train will actually arrive vs. when it's supposed to. That way you can run like crazy and get totally stressed out instead of just waiting. Or you can micromanage your life and lead a joyless existence staring into tiny screens awaiting the next orders from your technopuppetmasters. Whatever, man. Pick a flower. I thought you were cool.
