Continuity mistake: When the Charger turns off the paved road onto a dirt siding, it does so to avoid the cop approaching from the left on the side street. As the cop reaches the end of that street, he turns left to race alongside the Charger which is higher up on the dirt path. In the shot from the rear when the cop is turning, we see that he is already beyond the telephone poles that stand between the paved and dirt roads. When the shot changes to running alongside the police car, looking upward at the Charger, a telephone pole magically passes between the cars. Obviously, they started this shot further back.
