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

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

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

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.

The cars themselves are getting smarter and will be increasingly able to assist drivers - to the point where the cars will be completely automated.

I can't see a problem with imposing fines on drivers who violate traffic safety laws. The speed limit is the speed limit. A red light means stop. These things haven't changed since people got their driver's licenses.

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.
