My philosophy is: Everybody needs to look out for everybody else.

It would be helpful to be able to see the layout and for the maps to label what exits to use to get to nearby sites/buildings so you aren't wandering the station trying to read the signs in the crowds.

I'm surprised when I see someone doing the logical, commonsense thing: Walk facing the oncoming traffic.

Metro, built in the late 20th century, is the most escalator-dependent system in the world.

I think that maps showing platform details would be useful to visitors, especially to chaperones of school groups, etc. Also useful would be either a compass rose or an arrow pointing North at every metro exit. Emerging from underground is disorienting, especially at night.

I love the cameras and don't mind mailing in my check when I fail to pay attention and go too fast.

Nobody likes paying tolls. It's difficult to explain the concept of dynamic tolling, where the price varies to maintain the flow of traffic. And it's difficult to explain why highway widenings don't wind up helping commuters in the long run.
