Two thoughts about the recent posts by waremark and devonutopia:
One is to question the relevance of advanced tests for a driver who does not normally refrain from exceeding the NSL when overtaking, and might also break certain other rules from time to time. Suggestion: compliance with the requirements of advanced tests runs counter (in my mind anyhow) to the exercise of good quality, but uninhibted, judgement; and that's what advanced driving should be about.
The other thing is about minimising the time exposed to danger when overtaking. Minimising TED is a good policy of course, but what's wrong with staying offside longer than is strictly necessary when completing an overtake, so long as there is no danger in doing so? Many people seem afraid of crossing the centre-line and freely using the 'wrong' side of the road, and I see this as indicative of a relative lack of understanding and confidence.
Edit No. 3:
I see that Michael has also picked up on this 'wrong side of the road' business, and quite right too.
