So you're telling me I shouldn't bother to take a split-second to glance down the street, but instead...
...grab my phone, unlock it, navigate to the app, wait for it to load, wait for it to figure out my location, wait for it to make an API call, try to figure out which of the two "34th and 7th" stops is the one going in the direction I want (since it's a two-way street with bus stops on both side of the intersection), click on one randomly, confirm from the first bus destination listed that I did click on the correct direction, otherwise go back and click on the other one, and then look at its ETA?
Sometimes it really is just better to use your eyes, to figure out that the bus is going to reach the bus stop in about 30 seconds, and that it'll take you 30 seconds of brisk walking to reach it in time, so you'd better start making a beeline now.
