... is firstly to build rapport. So I get to know you, to be able to teach you better. And, from experience of about 300 students and observing 150 tests, you'll learn more easily because you get to know me.
The trust that usually develops means that driving happens naturally while we just have fun.
If you’re asking what makes me different, I’d say calmness, patience, lateral thinking, and genuine interest in your development. Plus the hat.
And does it matter if I don't know your driving history ? Not much. Driving instructors work likes dentists, not like doctors. Dentists don't need historical notes about work done before: what you see is what they take forward. (A doctor needs notes from previous physicians because they can't see what's "inside").
