Deliberate mistake: The VW beetles on the train are parked side-by-side. Cars are never loaded like this - they would be end-to-end to stop them overhanging the wagon and hitting passing objects. They're only positioned like that to facilitate driving the digger over them later. (00:07:40)
Deliberate mistake: When Bond walks through the tube train he leaves the doors open so the cameraman can follow him. This scene was shot several times to get the front and rear shots. When filming from the front, he closes the doors behind him. (01:30:30)

Deliberate mistake: In the chase through the tube station, Bond and Silva both slide down between the escalators. On the London Underground, this area has hard vertical signs at regular intervals, precisely to prevent people sliding down. (01:31:50)
Answer: Because Bond is fighting to the death with a man who's trying to throw him off a train. He can't exactly step out of the way.
