An automobile component that can be found in virtually every car, foreign or domestic. Invented by Mortimer Ford(Henry Ford's
illegitimate half brother or something), the hydroscillator's only known function is to allow vehicles to drive themselves in a semi-sentient manner. Although hydroscillator design varies, they are usually a fist-sized
cylindrical device with two wires sticking out.
