The way you are discribing the teaching is exactly the way you are taught to drive when in a HGV of all classes.
Just imagine what it is like to get a 45foot wagon round a very tight bend with a line of traffic on the other side of the road
That was all like you have discribed cola, imformation,position,speed blah blah blah......You will get used to it very quickly...
How long are the lessons you have been doing?
When i was training for hgv it was 8.5 hours a day for a whole week then a 2 hour test at the end....
