A pit crew is a team of skilled professionals responsible for servicing a race car during a pit stop in motorsport events, such as NASCAR or Formula 1. Their main tasks include changing tires, refueling the car, and making quick adjustments to ensure optimal performance. The efficiency and speed of a pit crew can significantly impact a driver's overall race time. Each member of the pit crew has a specific role, such as tire changers, fuelers, and mechanics. They train extensively to work together seamlessly, often completing their tasks in just a few seconds. A well-coordinated pit crew can be the difference between winning and losing a race.
