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.

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

If you're driving more than 50 mph through a neighborhood where the speed limit is 25 mph, I question whether you should keep your driver's license. You're a menace to society.

Motors that are vulnerable to shorting out because of snow ingestion should have snow filters installed over air intakes, and spare motors should be ready to replace any failed motors.

That's the original problem from which the escalator mess stems. There's just too many of them.

I don't like the midnight closing on weekends. It's one thing to tell people they have to drive to Jiffy Lube Live in the outer suburbs.

When I look at the faces of turning drivers, I mostly see them looking in the direction of oncoming motorists rather than at the people they're about to turn into.
