Backseat driver
English Idiom
Meaning: A person who gives unsolicited advice or directions, often in situations where they are not needed or wanted, much like a passenger in a car who tries to control the driver.
Origin: The phrase 'backseat driver' originated in the early 20th century when automobiles became more common. Passengers, often sitting in the back seat, would give unwanted advice to the driver, mirroring the way some people tend to offer unsolicited guidance in other aspects of life.
