To be fair, though, 50,000 persons per hour in subway capacity represents
packed trains with what might be called a degraded level of service. Your
analogy still holds, though, in that even under lighter loading conditions
the subway does a lot better, space-wise, than roads, and under heavy loading
conditions it does better travel-time-wise.
