A toothless traffic regulation like that invites disrespect for law and congestion in the streets. More to the point, it shows that many a traffic problem has a simple cure: change the law. Similarly, though critics contend that there is a kind of Parkingson's Law that causes any new car-stowing garage to overfill the instant it opens, many cities are making room for autos by insisting that new apartment houses and office structures have built-in parking space.
Solutions are even easier to find in the concrete-and-steel side of traffic handling: proven highway-building techniques are commonplace, and Washington has plenty of money. There will always be the time, of course, when 100,000 fatheads choose to clog the airport road just as some hapless chap leaves late to catch his plane; the traffic snarl can never be utterly banished. But in any pragmatic sense, the word for the traffic problem is: finite.
