August 2022 - Motor Sports Racing A trailing car (perhaps pushed by a line of drafting cars) uses the lead car's wake to pull up with maximum momentum at the end of a straightaway, enters a turn high, and turns down across the lead car's wake. On smaller tracks with fewer straightaways a car is tuned to have even more downforce to keep it stuck to the pavement and handle the turns better. For DFS NASCAR purposes, you must be aware of the scoring differences on DraftKings and FanDuel. Untold Stories: NASCAR's first Black driver, Elias Bowie.
