I didn't learn to drive till I was around 23, living in a small town in Gloucestershire. My driving instructor was pretty old school, not some BSM or AA driving school clone and had lived there all his life. From what I heard when learning from others, he'd taught most people in the town to drive.
Clive used to have lots of little sayings that he'd use when we were on our lessons and I wish I'd written them all down but there are two that I still remember every time I execute certain manoeuvres.
He used to think of a roundabout as a jam tart (stay with me here) and if I was going left or "straight over" he would remind me to stay on the pastry and not to stray into the jam. I was only to drive directly into the jam if I was going right and to drift back out onto the pastry after the exit before mine. Even now, if I inadvertently take the "shortest" route across the roundabout, mrs deadly might jokingly remind me that I didn't "stay on the pastry".
The second was when turning right into another road, I had to imagine a brick wall built on the centre line of the road into which I was turning, finishing at the junction. The idea being, if there was a wall there, I'd never stray into the "wrong" lane as I making the turn. Even now, when I'm making a right, I'll still sometimes say to myself "right, imagine there's a brick wall...".
Anyone else got any?
