Tambo....I first learned to drive when I was a young chap with BT. I learnt in a green Morris 1000 van ! It was in 1971 or 1972.
In those days, BT and Royal Mail had their own Instructors and examiners, although I am not sure if that is the case now.
I was sent on a intensive, week long driving course, with another apprentice. There was a little dicky seat in the back and he and I would change over every couple of hours. The Instructor would fall asleep, but would mysteriously wake up, if you went over 30 in a built up area !
"Slow down boy", he would mutter, before going back to sleep !
