When two cars come racing down the track on the final lap, the difference between first and second place is as thin as a knife’s edge. Until 1993, NASCAR officials actually used to time these photo finishes with regular stopwatches! Today, they use powerful and fast cameras and electronic timers instead. But no matter how you measure them, those finishes are still close.
As you can see in this infographic from Titlemax.com, the closest finish in a NASCAR Sprint Cup ever came down to a difference of two-hundredths of a second! It’s hardly surprising that these races can be so close and difficult to call when the cars are also moving anywhere from 100 to 150 miles per hour!
