Time for a fun short from the National Film Board, What on Earth!
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.
I always suspected that cars were the real earthlings, but this is a little too much!
