I don't believe any sort of traveler does a better job than any other sort of traveler at obeying traffic safety laws. It's difficult to foresee a camera program that can be used with bikers and walkers.

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

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

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.

I don't know of any source for online maps showing the platform, stairs, escalators, elevators, mezzanines and other station details.

I don't see traffic fines as a substitute for a commuter tax.

That's the original problem from which the escalator mess stems. There's just too many of them.
