6. A strong aversion to travel by foot (i.e., walking). Patients will use their vehicles (large, gasoline-consuming behemoths are preferred by KPD suffers) to travel distances in which walking would take less time than driving; thus, speed of travel plays no rational role in the manifestation of this phenotype. Also, a common delusion among patients is that travel to any location always takes twenty minutes. (Note: This tendency was reported to be characteristic as early as the 18th century and is thus one of the earliest-noted symptoms of KPD.)
