Some years ago, the National Film Board of Canada produced an animated film depicting an invasion of Martians to earth. Hovering over a modern city in their spacecraft, the Martians report back to their planet on the behavior of earth dwellers. The dominant species, they say, is a metallic organism of rectilinear form, whose locomotion is achieved by four wheels attached to the main body. These organisms, the Martians report, are capable of moving at great speeds, always along designated channels that appear to have been constructed to facilitate their movement. They eat rather infrequently, in feeding stations in which a liquid is pumped into their system. They seem to demonstrate great skill in moving about at high speeds, though at times they appear to misjudge, which leads to catastrophic collisions and destruction. There is one baffling question, the Martians report to home base. Associated with this four-wheeled species appears to be another organism, a two-legged species that inhabits the four-wheeled creatures and appears to be totally parasitic.
To us human beings, driving a car has become second nature. Popular myth holds that often dogs resemble or reflect the character of their owners. This is equally true of cars and their owners.
