I read a poem way back in elementary school in the 70's that described the observations of aliens watching cars on a highway and concluding that cars were the inhabitants of earth.
They described the "creatures" as moving on black "tapes" with white lines (highways) and having "guts" that were visible through clear panels in their fronts. (Human drivers viewed through the windshields).
The first time it was read to me as a kid, I didn't get at all that they were looking at cars and I've always wanted to go back and re-read it!
Does this strike a chord with anyone? I think the title might have had the word Highway in it...I never read the titles of anything.
