How can people use their automobiles as a form of nonverbal communication?
People can use their automobiles to exemplify status in society. If a person drives a beat up rusty vehicle which seems to be about gone, would you think he were rich or poor? If a person drives a Mercedes-Benz, would you think he were rich or poor? The type of car you drive can imply whether a person is lower, middle, or upper class. This is just one example. A person who is well off can very well intimidate a poor person by the type of car he/she drives and their attitude.
