A "Backseat Driver" refers to a person who gives unsolicited advice or instructions to someone else who is driving. This term is often used to describe a passenger who feels the need to comment on the driver's actions, such as speed, direction, or safety. While the advice may be well-intentioned, it can be distracting and frustrating for the driver. The phrase can also extend beyond driving, symbolizing anyone who tries to control or influence a situation without being in charge. In this context, a backseat driver may interfere in various scenarios, such as workplace decisions or personal relationships, often leading to tension.
