There's your first wrong buttumption. It's not. The System is essentially the same now as it has always been.
No. The strength of the system is that it has NOT changed and has managed to stand against all criticism and it is still as relevant and effective now and when it was first introduced. That's why it's still taught.
No. Unless of course you count the way that it is depicted or described in printed form.
Why? If it ain't broke...
You seem to be under the mistaken belief that the IAM define the system. No. The IAM and RoSPA teach The System as defined in Roadcraft. It is the basis of all police driving instruction from basic to Advanced courses.
Your stance is not arrogant or presumptious and if you really have something to offer then I have absolutely no doubt that the entire advanced driving world will sit up and listen.
Without any further tuition what are these sources of information that you have used? and having used them, how do you know that you're applying them correctly? Just because you haven't had an accident?
Certainly. So long as you recognise the fact that you may have spent a long time evolving and refining something that could well be fundamentally flawed.
It's not about anyone being superior or inferior. It's about what is the best and safest to drive a motor vehicle on a public road. That method has so far stood against all pretenders. It's is simply a case of getting the message across to you in a way that you can accept. Of course, the dialogue is a two way process and an instructor worth their salt should be capable of showing you how any why The System is the better way. It's not that you're necessarily wrong; It's that The System is better.
Nobody expects that of you (at least they shouldn't and it'll be pee-poor show if they do). It's about getting a particular message across. And in order for that to happen it requires that the receiver be at least open to reception.
