He revs up to amazing speed, though barely keeping ahead of the rock. Finally, Daffy slides to a halt and, disguised as a traffic cop, causes the rock to wait while a swan crosses, as though at an intersection. After that, Daffy waves the rock through and takes off in the other direction.
In this cartoon sequence, the speeding character rapidly gains speed, only staying ahead of an unchanging entity. Eventually, Daffy stops and, pretending to be a traffic authority figure, instructs the stationary entity to wait while a bird crosses the road, treating it as if it were a crossroads. Afterward, Daffy signals for the stationary entity to proceed and then speeds away in the opposite direction.
