Corrected entry: Dennis and Neville are push-starting Oz's car after they have stopped for a break. This wouldn't help, as the car has an automatic gearbox. The automatic gear selector on these cars (Ford Zephyr) is on the steering column and can be seen when they break down on the motorway.
The Accused - S1-E6
Corrected entry: In the police station, the police officer is yelling loudly at Neville in German. Why didn't they find an interpreter as it is obvious that he is a British builder who probably speaks very little German? Also, why would you get aggressive with someone who is obviously scared?
Correction: Just becuase someone is English doesn't mean they can't speak Germen, at the initial 'interview' the officer may have just thought that Nev was faking not being able to understand. He wasn't being aggresive, it's just the way German happens to sound to English ears, I know I hear German voices all the time and it often sounds as though they are shouting and being aggresive.
Correction: In fact you can push-start an automatic. Instead of popping the clutch, which you don't have - when you get up to speed you drop the shift from neutral to drive. Not good for the gearbox, but it works.
