Driving to me consists of two skills: Car control and traffic. You can be a master at drifting or hammering out low lap times, but still be a danger on the public roads, and you can be a good reader of traffic but have no clue as to what to do if you truly need to control the car at or past it's limits.
Traffic reading and defensive driving is most of the battle. It keeps you from having to use all the capacity of the car. But, things happen. And when they do, knowing how the car will react to emergency inputs and having the confidence and skill to remain in control can literally save your life.
My plan of attack for my daughter consists of building her skills in both areas. She will learn to read traffic from me and from instructors so that she won't be limited in her strategies. Then she will hit the auto-x course and learn to push a car to it's limits, and past them.
We're also fortunate that she has a variety of cars to learn on, including a very primitive RWD car with no ABS, no traction or skid control, a manual transmission, and a chassis that rewards skilled inputs; a large AWD SUV with all the electronic nannies but requires thought in terms of cornering speeds; and following distances and a FWD compact sedan that is very benign to drive but is challenging in terms of seeing around the large vehicles that dominate our roads here.
We've spent some time on the track in carts, and she has a good sense of motion, speed, traction, etc. The next step is the full sized stuff...
