"The effect of riding in automobiles on the perception of pedestrians, bicyclists, and other motorists demonstrates that spaces can banish people to an alien universe even when those others are close by. People who are usually good-natured and gregarious are often likely, as motorists, to resent, berate, and sometimes even attack pedestrians, joggers, and other motorists who occupy the road. The key condition that facilitates this result seems to be that people are enclosed by different spatial boundaries, are moving at different speeds, and have no adequate mode of communication and little mutual understanding about how to stay out of each other's way in unforeseen circumstances. Psychological isolation occurs in spite of total visibility. Indeed, this is the kind of visibility that increases alienation because, like visibility in a prison or psychiatric ward, it is experienced as surveillance and threat. In such settings visibility and proximity only emphasize the impossibility of communication." - Murray Edelman, taken from From Art to Politics: How Artistic Creations Shape Political Consequences.
