New York City Observation #1
In New York City when the subway doors open a crowd rushes to board the train whether or not there are people waiting to exit. The best that disembarking passengers can hope for is to have half the doorway left clear by those on the platform, who make it very clear with their expressions and postures that it injures them greatly to be forced into this concession. I'm sure people do this in other cities, but I imagine that, like many things, this problem is bigger in New York.
Well now it's spreading. Yesterday I took an elevator downstairs in the office building where I work, and when we reached the ground floor, several passengers squeezed into the elevator before those of us onboard could exit.
I can't wait for this to start happening with taxis.
