Visible crew/equipment: When the trucks have been circling the diner for about 20 minutes, in a leading shot of the big green goblin head on what appears to be the main truck, you can see a light coloured car in said truck's shiny metal bumper, but there are just trucks in the circle of possessed vehicles. The truck in front of the green goblin head truck isn't that colour either.

Answer: It should be noted, the ending title cards seems to set it up so there are no plot holes and answers any "why" questions (which, intentional or not by King, can be debated). While the opening premise is the comet's close pass by Earth caused all machines to turn on people, at the end, the Russians blew up a UFO 2 days later, suggesting that it was the aliens controlling the machines. Bill suggests aliens are trying to wipe out humanity (although at that point he's just guessing and had no evidence of an alien or UFO present), but it can be debated the actual premise was that aliens were just testing or experimenting on people.
