 At one point in this episode, the dispatcher addresses Dan as "Mr.  Mathews". This was somewhat unusual, since the writers for the show  typically avoided situations in which he was addressed by name or  title by any of the Highway Patrol officers or employees. Different  state Highway Patrols have different names and organizational  structures, and they also have varying titles for their commanding  officers. Even though the California Highway Patrol provided  technical advice and assistance to the show, the scriptwriters used  a generic approach in order to avoid the appearance that any  particular Highway Patrol organization was being favored.
