There is also the factor of luck, not everyone has the same experience during these exams. Sometimes you're the last student that the examiner has to do for the day, and you can reach a point where all he wants to do is just get it over with and not be as diligent as usual.
The luck factor is definitely there. I know someone who failed their exam because of an issue at a pedestrian crosswalk. Had there not been a pedestrian attempting to cross at that exact moment, the boo-boo would never have happened. There is a certain amount of randomness to driver exams based on what traffic conditions appear etc.
At the same time, the examiners have their tricks, They know the location of every oddball regulatory sign in the area, and can vary the route to take a marginal test-taker past the trickier signs, to see if they spot and comply. An easy way to justify a fail if the candidate is borderline.
