As Oliver Pope is driving home he glances over his right shoulder. Then the accident occurs and he leaves. As he's driving away, the producers use the same clip of Pope looking over his right shoulder.
The front bumper on Oliver Pope's car appears and disappears in the last scene.
In the final driving scene, the car's headlights are intact even though Oliver smashed the headlights and the horn with a hammer earlier in the garage.
By the time the witness arrives on the scene, Oliver Pope is already in the vehicle which is facing away from her and is completely different from the one driven by Pete Radcliff who she was certain was responsible for the hit-and-run.
Within the first few scenes, we see Oliver's 1956 Ford Fairlane 2-dr sedan with rear fender skirts. Later when his wife, Lillian, attempts to drive the car through the intersection of 3rd & Park (and subsequently breaks down and stalls) the Ford still has rear fenders skirts. In all remaining scenes, however, the skirts are absent.
In the opening scene when the paper boy falls off of his bike after colliding with Pope's car, he rolls onto the ground where there are no newspapers strewn about and his bike is undamaged. However, when Pope exits his car to check on the boy, there are newspapers strewn about and the bike's front wheel is severely damaged.
As the car pulls itself out of the garage toward the end, the outdoor set lights are clearly reflected in the car windows.
The site of the accident is frequently given as "3rd & Park", but the announcer on the car radio at the end says it occurred at "3rd & Elm".
Pete says that the unknown driver left the kid "just lying there in the rain". It wasn't raining at the time, though it did so in a subsequent scene.
