Ally,
i am glad that you are enjoying the course.
I agree with what you say about it being a part of the learning to drive process. This is often a comment put on the feedback forms at the end of the course, but when we say this the view seems to be: " you are a training organisation.... of course you will say there should be more training"!
Realistically there are 2 problems to this approach. Firstly there would be a big difference to the mental attitude of people attending. At the moment it is people who have lost their licence, realise they have done wrong and want the carrot of a reduction in their ban. Contrast that with learners attending a course who think "I wouldn't do that anyway" and are getting no tangible benefit, other than it has to be done. They would be much more resistant to the training.
Secondly there is the problem with scale. At TTC we educate up to 10,000 drink drivers a year. There are about 54,000 people convicted a year, and 20-25,000 of them do a course. Contrast that the last figure that I saw for people taking a test per year, which is about 800,000. The logistics of arranging this, and finding the people with the skills to deliver the training, would be huge. There was an outcry a few years ago when the driving test was increased to include an element where you had to show you know where to put water and oil and how to check the tyres. Imagine the reaction when people are told that they have to take a couple of days off work to learn about drink driving..... which in their perception is something they would never do.
So whilst I agree with you, in reality it will never happen.
