A Pit Stop Fiasco: A Tale of Teamwork Gone Awry, Redundant Equipment, and Unfortunate Luck
Example of a pit stop gone wrong was for Valtteri Bottas, the Mercedes AMG Petronas driver who was leading the Monaco Grand Prix (2021),and was on the cusp of a potential victory. As he entered the pit lane for what seemed to be a routine pit stop, no one could have predicted the twist that was about to unfold. The Wheel gun damaged the lug nut on his front right tire. He had to retire after just 30 laps into the race. Despite efforts to remove the nut, it had to stripped, rendering it impossible to dislodge on the spot. Post race analysis revealed that the pit crew at the front right ,angled the wheel gun at a higher angle which grinded the teeth on the wheel lug nut. This made it impossible for the crew to remove the tire. The complexity of the situation led the Mercedes team to transport the car to their U.K. factory, where heavy-duty machinery could eventually break it loose. Mercedes’ F1 team head of strategy, James Vowles, explained that the decision to handle it at the factory was driven by the need for specialized equipment.
