Imagine a transit system that kills more than 260 people every year in one metropolitan area, maims and seriously injures another 2,600 or more, and forces those who survive to waste more than two hours every week in unscheduled delays. We would demand an immediate shutdown, of course, followed by a radical change in culture and oversight. Except … we have such a system, and we demand no such thing. It’s the system of roads and highways in and around the nation’s capital. And it’s not all that different from the system of roads and highways in any other metropolitan area. Why are we so much more forgiving of their punishing costs than we are of the transgressions of Metrorail and other rapid transit systems?
