Hora, are you a driving god?
I suspect you are not, no matter what you might think about yourself, so please just stop making irrelevant suggestions.
Attitude plays a big part in driving well, not the ability to talk a good drive and fantasise about your extreme car control skills (or even mountain bike skills)on various internet forums.
IAM/Rospa are good organisations that aim to get people to a high standard of safety whilst making reasonable progress.
I did the IAM motorbike course (and a Corporate IAM driving course) and found it worthwhile, even if I was aware of much of the content beforehand. Being observed and tested is a useful experience in itself. Some people might be afraid of what they might hear.
By all means disagree with some of their dogma/mantras, but they teach a solid, safe method of driving -If not necessarily exciting, dynamic or particularly ‘advanced’ in the sense of extreme vehicle handling.
