Wrote this in the Cycling forum discussion but guess equally valid here
what I in answering Martin in the Cycling debate wrote:
I will post this to the related thread as well.. but the Chief of Driving Instructors did say that there is a tendency to practise only on the test routes so that the student driver will drive according to the rubric of the test and then be "lost completely" on new and unfamiliar ground when left to own devices - making silly and even tragically lethal mistakes. In fact, he echoed something which I posted to vonhosen on the PH site on this same topic .. when I described that the reason why we did the block lessons with our kids and then had them out with different family members in very different areas and times of the day was giving our young a varied experience routine and then tightening up in the two days before the big test day itself on the test routes. Could be why Durham's trainer was so far from "base" as well

The real test of "understanding" lies in the "unseen exam" where you apply what you have learned - and show and prove you have understood it.
The guy said exactly what has been said by most of us and certainly by Paul

....that drivers need experience and can only obtain this by driving on different roads and even the familiar roads in different road, time and weather conditions. Hence the call to allow the kids to practise earlier and for longer before being of age to take a driving test. It would help if after these lessons .. these children were taught to
evaluate their drives and how they might improve and learn more in formal lesson time .
Like Ross.. our three eldest did have the benefit of varied well able and enthusiastic motorists across our family and did benefit very much from lessons with the family BiBs. They have been brought up with a strong sense of "safety and responsibilty for selves" - and all our kids are very proficient and quite fit cyclists anyway

and our youngest aged two now .. just loves tearing around our garden and the local park areas on her trike and a bicycle with stabilers

She already shows abilty to steer and seems well able to judge speed and distance within her own "speed" range already.

on her bikes and pedal cars and so on..

OK .. so it's around 5- 10 mph .. but she's only a tot.. and my paternal pride is overflowing here
But.. lessons for the three young drivers began when they were 14 years old. We got them to take note of our driving and what was happening out there on the roads. We had them on tracks and go-karting sessions to "get some feel of higher power, speed and handling" which is of course very different from handling a bicycle
This was followed with the Highway Code and the Hazard Aware DVD games which we used more to look at the clips and discuss the developing hazards as we know real life situation is a far cry from clicking a mouse in a controlled envrironment. We then extended this to getting them observe the roads when out with us .. and just asking in much the same way as Ern apparently does with his kids.. what hazards, if any they could see as "potential" and just asking general observation questions - which we followed through when they were actually practising their drives with us.
Lessons were purchased in blocks .. We arranged for lessons at different times of the day .. and the initial block was designed to get "handling and feel" prior to practise with various family members and then a final block aimed at pure training on the rubric of the test on the test circuit.
When they passed .. we gave time for the euphoria to pass .. and then went out with them and their "solo" was with us following at a discreet distance
I think I have done everything I can to set them on a safe , steady and enjoyable driving career. The eldest already has taken and passed IAM and RoSPA courses and the twins have not only a sibling "rivalry" but also a strong and safety led desire to match him and ourselves
