Do Zombies go instantly stupid? You always see them walking around with their hands streched out, looking for some brains to eat but you never see them use any tools; a chimpanzee uses tools. Why can't they drive a car or shoot a gun? What if the zombies raided the local armory and drove off in a tank? I think if we rely on the hollywood definition of zombies, then someone will have vastly under-estimated the enemy.
