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.

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

Metro shows no signs of being able to make its trains run on time. This occurs during single-tracking and it occurs during normal rush hour service.

Many Saturday mornings, I take 495 from Fairfax to Maryland in the morning, and I'm astonished by the speed of many of the drivers. Even when I drive 70 mph, I'm being passed by people driving 80-90+ at times.

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 wish the dashboard indicators for lights were standardized throughout the auto industry.

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.
