How could the track be responsible for certain drivers having bad passes, while simultaneously allowing other drivers (Jim) to do better than normal? That's not how that works. Buddy and Rosalee are both very new to the track and not very experienced, so it makes since that they would screw up a turn or something along those lines. Jim just finishes a brand new truck that he is debuting this weekend and it's not full of technology older than time itself, so it would make sense that he would improve. Is it too hard to accept than an underdog beat the favorite?
