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.

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

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.

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.

As our eyes age, they have a tougher and tougher time adjusting to rapid changes in lighting, and we need to be aware of this.

Over the decades, you got various companies involved in making escalators and you've got Metro varying between internal repair crews and contractors. They're dealing with old equipment, which of course is prone to break down, and the repair crews don't even know what's busted or who made the busted parts till they tear the things open. Then sometimes they have to go back to the shop and manufacture parts, because the original maker has gone out of business.

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