Part of Erin’s job was to let people know when they had reached the final lap of the four allowed on the Lola track. To signal the drivers, she waved a checkered flag. Often, people completely ignored it. “Sir,” Erin would say. “Please return the car to the starting line.” “Fuuuuuuuuuuck . . .” the drivers would say before disappearing around a curve and out of sight, then zooming back into view to add, “yoooooooooooou!” The honor system was clearly not working.
