Finishing more than ten minutes ahead of newly-second place Tetzlaff, Dawson completes another two laps for good measure upon fear of a scoring miscue. Sometime thereafter, DePalma and Jeffkins finally bring their car across the line, but in twofold futile endeavour: Speedway rules, requiring that all entries move under their own power, mark DePalma's final number of circuits at 198, and the push across the line, even if to be counted, bringing them only to the beginning of the final lap.
