Instructors teach yoiu to pass a test, they don’t teach you how to drive, even IAM instructors do the same, and who’s say so is a IAM driver better than a lot of drivers on here with a wealth of experiance.
True, in general, for the DSA tests.
Not true I’m afraid on the IAM point - the idea is not to pass a test - sounds crazy but true.
The idea of advanced driving is to learn a different system of driving which, in turn, creates a safer driver.
I have had a few associates who learnt the system and became safer, better drivers but never took the test - so what
- they are now safer & better drivers who are on our roads

Is an IAM driver a better driver than those on here? - I don’t know - I would have to be in the passenger seat for a while to determine that.
Certainly, there will be differences in the types of experience but that is not what advanced driving is about. It is about the attitude, style & manner of general on-road driving to which the IPSGA system is designed to enhance.
There will be drivers on here who have great attitude, style & manner of general on-road driving but do not consciously follow the AD system but may still be doing it - or very similar.
The easiest associates that I have had in the past have been LGV drivers - why - because, in general, they have a greater understanding of what can happen out there on the roads as well as subconsciously following a safe system - it might not be EXACTLY the IPSGA one but it is usually very close to it.

Another point - the DSA don’t like the AD system in general as it throws out a lot of what they teach & examine for.
When instructing for LGV, I use the AD skills for anticipation & observation but teach the DSA methodology - it does get fun when doing demo drives as I have to remember which type of drive I am demonstrating and not mix the two styles as it could confuse trainees

To get a better understanding of driver progresion including attitude & beliefs, then a read of the book ‘Mind Driving’ by Stephen Haley is a must.
