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

Back in 2011, when the weekend maintenance disruptions got more aggressive, we were told that the work on weekends and at night and midday would be enough to get the system back to a state of good repair.

If the Metro general manager, Paul Wiedefeld, says those extra hours for maintenance are necessary to help fix the system and make it safer, then that gets top priority.

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

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

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.

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