Ambient temperature in the Herald Square station (one of the biggest) in the summer is often well over 100 degrees, humid, and stagnant, while the platforms and tracks are filthy and smell like mold and pee everywhere.

There's no way to tell when the trains are coming. 5 will get you 10 this tax does nothing to improve the subway.
