The article itself is firmly tounge-in-cheek as evidenced by the following quote:
But there are a couple of crucial elements in the design of this world that point not to a human overlord, but an all-powerful Designer with a bad case of motorhead……if one looks closely enough, cloud formations resembling tire tracks can be seen drifting through the sky. Certainly, it’s no mistake that this most befuddling design element is also the most heavenward. There’s something up there, and It won’t be explained. But It does have a name, and we can thank the tractor trailer character Mack for this revelation. Upon finding his lost friend McQueen late in the second act, he exclaims, “Thank the Manufacturer!” Must we?
The entire thing is well worth a read, especially the comments at the end from those who failed to completely grasp the joke.
