I was pretty confident that I understood how to use the basic contols of a car before I had ever put the key in the ignition.
The reason quite simply was that I had been in the car observing my dad drive for years. Watching his feet move the pedals and his hands shifting gears, I would listen to the engine sounds as the car increased and decreased speed.
Before choosing your instructor and while waiting for your provisional licence, begin to observe the road and other drivers while you sit in the car. And when walking along the street watch how the traffic flows at juctions and lights.
Putting a price on the experience I gained watching my dad all those years ago and the effect it had on the total number of lessons I took is difficult. But there is no doubt in my mind that it made a massive difference.
Try it out, it might save you money on driving lessons.
