Days of Thunder (1990)

Other mistake: After the drivers enter their cars at the Daytona 500 at the end, there is a shot where Russ Wheeler's #18 Hardee's car is in the inside lane and mid-pack a row ahead of Cole's car on the outside. In the overhead shot as they get the "start your engines" command and the shot immediately following, you see Cole on the inside and Russ on the outside of the last row. This is compounded because they show Russ looking to his right and Cole to his left at each other indicating that they have reversed sides again. Also, Russ starting mid-pack would not be feasible and back of the pack unlikely since they said he won the pole. Even with the Duels races setting up the lineup, the front row qualifiers still stay the same at Daytona. Russ could be at the back if he made changes to his car (which Cole did). Not sure if either of those rules were different in 1993. Along the line of the Duels, the plot seems to imply it is Cole's first time back in the car and he is nervous. However, he would have run in practice and his duel race already by the start of the 500.
