Qualifying sessions are crucial events in motorsport, particularly in series like Formula 1 and NASCAR. During these sessions, drivers compete to set the fastest lap times, which determine their starting positions for the main race. The better a driver performs, the closer they start to the front of the grid, giving them a strategic advantage. Typically, qualifying sessions are held on the day before the race and can vary in format. For example, Formula 1 uses a three-part knockout system, while NASCAR has a single-lap format. These sessions are essential for teams to gauge performance and plan race strategies.
