Cones: turn in, apex and track out, or not?

[AMoore]

I am a new student with only two events under his belt.  I realize the dangers of tunnel vision, and jerky movements, but I believe the pros outweigh the cons.  Moreover, the experienced drivers should be able to avoid these pitfalls.  I thing the beginning driver with the help of his instructor benefits from understanding how following the line makes for a better, safer driving experience.  The instructor can more easily explain this by referring to the cones.  Of course the instructer still needs to remind the beginning driver that the cones are only a frame of reference, and one must not jerk into a turn at the first sign of a cone.  A beginning driver must also be warned that cones tend to move.
