Character mistake: Jimmy is at work, feeling sick in the toilet. Two other employees are talking at the sinks. The man on the left is called Phil by his colleague at the beginning of the scene, but at the end of the scene, he calls him Simon.
Continuity mistake: Jimmy crashes his scooter into a post office van. The rider is a stunt double who looks older than Phil Daniels, who played Jimmy.
Continuity mistake: When Jimmy is riding along the cliff, the GS Scooter has a fly screen on the handle bars. When he rides back to take the long run up before jumping off the cliff, the fly screen disappears only to re-appear a couple of seconds later.
Factual error: The station scene shows a Class 50 Locomotive which did not work from Victoria. Looks more like Paddington Station. Victoria is the main station for the Brighton line.
Revealing mistake: When Jimmy's mum draws back the curtains, a British Rail Class 43 (HST) goes past in the background, only in service since 1976. (00:43:51)
Continuity mistake: When Jimmy meets his old school pal Kevin Herriot at the public baths, Kevin's hair is quite short, but in the cafe after his bath his hair is long and bushy in a DA style.
Answer: Yes, you're right! The last scene shows a scooter with no windscreen.
