I don't see any possible excuse for any driver anywhere to endanger people.

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.

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.

Nobody likes paying tolls. It's difficult to explain the concept of dynamic tolling, where the price varies to maintain the flow of traffic. And it's difficult to explain why highway widenings don't wind up helping commuters in the long run.

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.

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

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.
