Engine idling sounds are a staple of stock sound effects libraries because editors constantly need believable vehicle ambience without recording a real car. This longer running clip became popular for video, game, and animation work where a short loop would sound repetitive and obvious. Creators use it for parked cars, waiting scenes, and slow drives, and it is also shared on soundboards as a simple prank and background gag, playing car noise from a phone or speaker to suggest a vehicle is nearby or about to leave.
