"Prius Missile" (Japanese: プリウス・ミサイル, Hepburn: Puriusu-Misairu) is an internet slang term originating from Japan in the 2010s. The term is used in Japan to describe the Toyota Prius as a "missile", as it is driven by older drivers who have been involved in traffic accidents and crashed into buildings. The slang term is thought to have emerged from the prevalence of Japanese news reports showing images of the Prius involved in traffic accidents caused by sudden unintended acceleration, such as the Higashi-Ikebukuro runaway car crash in 2019.
