A household across the street from me has five residents: mother, father, employed daughter, twin sons in high school. They have at least three cars now, and I'm pretty sure I've seen four (one, to be pedantic, a pickup truck). A household next to me has within the last five years had three residents: mother, father, son then about twenty. They had three cars. A household down the street: mother, father, employed daughter, employed son (the last there part time). All have their own vehicles:sports ute, truck, sedan, truck. It is possible that a household at the end of the block, mother, father, daughter in high school, has three cars; but I'm not sure whether father and daughter use the same car or a different one. We are in a city, close to public transportation. I suspect that as one gets farther out into the suburbs, one finds more households with three or more cars.
