Rayma Rich’s “collapsible riding companion,” patented in 1991, offers female travelers an inventive way to deter criminals: Set up the false head and torso in your passenger seat, dress it in a suitable shirt, and you have a devoted male escort who will accompany you anywhere and never ask for overtime.

When you get back to the airport, disconnect the head, stow it in the torso, and “the riding companion becomes a lightweight, easy-to-carry rectanglar case for traveling.”
