On a related note for anyone who has walked around both Manhattan and downtown Chicago...
Ever notice how downtown Chicago has much less noise of honking cars than downtown New York City? A friend pointed out it's because of Chicago's lower-level streets[0] that a lot of service vehicles use for loading/unloading. That's in contrast to Manhattan where everybody has to share the same street level. E.g. a brown UPS truck that stops for a mere 20 seconds is enough for the yellow cab driver that's stuck behind him to smash on the horn with impatience.
