There is nothing worse that I know of than trying to move through traffic. It is the price of living in the big city, and Griswold is no exception. The military presence make it even worse.
Since the war has been going on for so long, there are plenty of people who don’t even think about it anymore. It just blends in with their daily lives. They find ways to cope. Our hero has found a way to cope with the traffic; it’s why he has the motorcycle. He also seems to have a pretty healthy disregard for authority. Say what you want about that, at least he is trying to get to his destination on time. I could use a little more of that.
