Continuity mistake: When Stan stops the bus to collect his washing from the laundrette there is a white mini parked outside the laundrette with a brown car parked in front of it. But when Blakey confronts Stan coming out of the laundrette with the bag of washing, the brown car has gone without enough time for it to start up and drive off.
Continuity mistake: The female driver is chastised by the general manager for following the wrong diversion signs. At the end of the preceding scene, we see the bus VNO 862 with a saw advert. This advert is white text on a blue background. When the bus pulls up to the inspector and general manger, the advert can be just seen in the top of the shot. It is now brown on a white background. Plus it's now bus WNO 476. (01:05:25)
Continuity mistake: When Stan sends a female driver on a fake diversion route, in the first scene the driver gets into bus WNO 476 (a no. 33) - the bus has KP nuts ads on the front and sides. In the next scene we see bus VNO 862 (a no. 13A) with Lyons maid and SAS adverts. This bus is then used for the remainder of the diversion gag, with close ups of the same female drivers as at the start. (01:04:10 - 01:05:25)
Continuity mistake: When Blakey sees Stan go into the launderette to collect his washing, there are two men watching from the balcony of the shop next door. When the angle changes as Butler comes out of the laundrette, the two men on the balcony have gone.
Continuity mistake: Stan and Jack are watching the women drivers eating in the canteen and compare them to Russian athletes. The blonde woman and the grey haired woman change position at the table between shots.
Continuity mistake: When Stan is getting away from Betty's husband he demolishes a telephone box and a bus shelter in the bus. When he first gets in it has a white steering wheel but in all the following shots in this sequence it has a black steering wheel.
Continuity mistake: When Stan's bus pulls up opposite the laundrette there are loads of children watching from the balcony above the shops, but when Stan enters the laundrette the kids have all gone, and when Stan returns to the bus the kids are back on the balcony.
