In the "Almost Always True" number in the car, there is a bad cut when Maile's hands change position on the steering wheel and Chad's left arm goes from propped on his seatback to stretched out behind Maile.
When Chad first goes back to his parents' home and Ping Pong drops the hose, in one shot it is spraying water at the front tire on Chad's car. In the next shot from a different angle, it is spraying the back tire.
In the pineapple field scene, only Ellie remains in the car (clearly seated in the back seat on the driver's side) while the others get out to get some pineapple at the nearby stand. Just a few moments later, Chad returns to the car to bring some pineapple to Ellie, who is now seated on the passenger side of the car, a break in continuity to facilitate the camera angle and dialogue.
