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

Tolling plan is a wonderful opportunity for political pandering, and some candidates are taking full advantage of it.

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.

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

When different generations of cars are combined into one train, it messes with the loudspeaker system.

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.
