During the car chase a road maintenance man painting a white line down the middle of a road gets bumped from side to side by cars speeding past. The can of paint that he is using moves between the initial wide shot and the close-ups of his feet. Also, the portion of line that he is painting in the close-up shots disappears in the final wide shot of him with the paint can on his head.
The film set that was used for the town centre street changes between scenes: in most scenes there is a side road Westgate Grove between the County Bank and the shop called Brenda's which has the distinctive wooden fascia boards above the windows, but in a few scenes such as the one where Troon and the examiner return to the driving test centre, an extra building has been inserted in the place where this side road is. Also, in the background beyond Wells Cycle Co, some scenes show a building whereas other scenes show a fence.
