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

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.

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.

There are easily accessible programs to help aging drivers maintain their skills, or recognize when they need to give up their cars.

Many police officers watch for vehicles without headlights because it's a telltale of a drunk driver.

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

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.
