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 the vehicle is ready to return to the race as fast as possible. Each member of the pit crew has a specific role, such as tire changers, fuelers, and mechanics. The efficiency and speed of the pit crew can significantly impact a team's performance, as even a few seconds saved during a pit stop can lead to better race results.
