Unlike other metropolitan areas, the subway and bus network in New York can actually get you pretty much anywhere, relatively quickly. In theory. Unfortunately, this marvel of modern transportation is often hindered by an endless supply of construction delays, outages, and rerouteing. Sometimes, your train will sit in the middle of a tunnel, in the dark for several minutes, just because.
The MTA wouldn't leave you blind, though. Instead, they blindfold you and spin you around a few times with indecipherable PA announcements seemingly recorded on Edison's original phonograph and omnipresent detour instructions you'd need the Rosetta Stone to interpret.
