also, that bus is there across a few years of street view. Why the heck does NYC need school busses in a dense city?
If it's there that consistently, it might live there (is that a school over on the left?). But even schools that don't regularly collect students with dedicated school busses might want to have some for taking groups places, either transporting them between buildings in the district or for field trips or similar.
This is objectively the correct answer to the problem.
