Now real time subway countdown can be accessed from the surface: via either android/apple app.
This is certainly helpful. Only MTA could do this since the data is not publicly available.
On the side story, this initiative is what perhaps makes me think twice about those programmers in Starbucks. But then, I've never quite seen such, only read about them, and preachers who go to this high class coffee place to prepare their sermons.
Nevertheless, a $4 coffee is really unnecessary and I still believe many go to these places to avoid troubles at home.
