An animated short from 1966 via Canada's National Film Board (NFB)

> This animated short proposes what many earthlings have long feared – that the automobile has inherited the planet. When life on Earth is portrayed as one long, unending conga-line of cars, a crew of extra-terrestrial visitors understandably assume they are the dominant race. While humans, on the other hand, are merely parasites. An Oscar® nominee, this film serves as an entertaining case study.
