## Origin

The term originates from the humorous suggestion that the steering wheel attachment allows a driver to operate the vehicle with a single hand, thereby leaving the other arm free to provide romantic attention to a companion. This manual convenience reportedly facilitates the act of necking while in motion, a social arrangement which evidently prioritized the passenger’s comfort over the driver’s adherence to standard safety protocols.
