A related problem is the political pressure to keep the single trip price artificially low, under the excuse that it's on behalf of the working poor. And yet the working poor buying single trip tickets, because they can't afford monthly passes, end up paying more per trip than someone who can afford the monthly pass. So the policy doesn't even meet the goal that the policy purports to shoot for. And still another problem is that the system capacity is insufficient for demand. The design has reached it's scalability limit. We need transporters in NYC, or something, at this point. A continuous running conveyor-belt "people mover" like in airports might be more efficient.
