I’ve taught a half dozen or so people to drive manuals. Each one did something I’d not have expected. My favorite was the person who pushed the clutch down only as far as they pressed the brake when coming to a stop. Of course the car died. Once we could break that habit they did alright.
I pretty much just start with having them stall the car to prove the world doesn’t end…it’s fine. It’s gonna happen a dozen or so more times. Let’s move on.
There was a point when everything I owned were manuals. Went to visit my parents and had to drive one of their cars. Got in and went to start it and thud! I instinctively went for the clutch and brake. Right foot found the brake and my left foot found the floor.
