 The idea behind the episode came from a study performed that showed women had more cases of road rage than men . The names of the other car salesmen on the board in the car garage are friends of Mike Scully from high school . The road rage film which Chief Wiggum shows during the road rage class was originally titled " Screaming Yellow Honkers " . The road rage film was originally to have been presented by Troy McClure , but voice actor Phil Hartman died the previous year . The group of people running out of the zoo , before Homer , Bart , and Lisa , are caricatures of Mike Scully , his wife , and his children , who are also seen running behind Kent Brockman 's news report . The Fox Broadcasting Company executives were displeased with the positive references to NBC made near the end of the episode . As a compromise , the writers added in the sequence during the end credits where Homer reads a statement that disparages NBC and praises FOX ( and briefly praises CBS ) .
