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 don't see traffic fines as a substitute for a commuter tax.

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

Many police officers watch for vehicles without headlights because it's a telltale of a drunk driver.

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.

Seems like people could behave themselves without making a calculation regarding how likely or unlikely they are to kill other people.

Drivers tend to look for other drivers, rather than for pedestrians or cyclists.
