As a friend used to say, I can explain it to you. I cant understand it for you.
The Doogle School of Driving apply here...Two sessions AM/PM...
Student in the AM class drives a car
observing all traffic laws...first error results with a gentle tap with a
stick on the top of the head from the instructor sitting in back seat ( safety helmet provided for student)...
Increasing errors result in
increased force with strike.
Break for lunch...
PM session we remove the helmet
