(acronym) Cager Internet Defense Force. A play on words referring to the JIDF (Jewish Internet Defense Force, which is a real organisation). Cager refers to Death-cage rattlers, i.e. car drivers, from the perspective of a committed cyclist. The CIDF supposes the existence of a coherent organisation that leaps to the defense of car drivers in forums across the internet, whever a cyclist complains about being run over or weak penalties applied to a driver that killed a cyclist, or any participation in the frequent online conflicts between cyclists and drivers. See: Comments section of any newspaper column about cycling or traffic since about 2005.
