Continuity mistake: To beat the traffic, Coop skateboards inside a construction pipe. The pipe is on the back of a truck, so it's not exactly very long, and gets picked up by a crane arm mounted on the truckbed itself. However, Coop takes ages to come out of the pipe, and in the shot from inside the pipe it looks as if is dozens of meters above the street level, which isn't. (00:08:00)
