What metaphors are used in 1Q84 by Haruki Murakami?

In Chapter One, Aomame is on an unknown errand, and the symbolic and metaphorical imagery is broad and apparent. While stuck in a traffic jam, Aomame realizes she's going to be late for her meeting. Aomame is patient and waiting -as are the other people waiting for traffic to move. She is one of millions, each in their own car (their own world) all waiting on the highway to get to an unknown location (the dreams and desires of each), though ultimately all of them will end up home (death and Heaven). These people are inside the cars, each trapped in his or her own world, and they are disconnected with one another because of it.
