KIT gets destroyed by the big machine, watch for the front wheel before the show goes to the commercial, after the commercial, watch that wheel again, you will see that is different.
Right after the black T-top was destroyed by the battering ram, we notice the passenger's side front tire was still holding air. When the commercial ended the tire was flat so it is only natural for a hub cap to fall off, especially the black T-top bowling ball hub cap. Production error, I think not. Cause of nature, guaranteed!!
