Re: Driving instructors and learners - do they drive like each other?

How on earth did they deduce 11 percent? Did novice driver collisions really fall by that much overnight when HPT was introduced?

Related, I suspect some instructors get their pupils to change to second gear too early because they have trouble with allowing enough time for the engine speed to fall when going into second. This then lives with them most of their driving lives, as I've found out talking to an IAM local observer assessor
Entering a roundabout I'd much rather see the driver accelerate in first to the point they're no longer side on to circulating vehicles, whereas rather too many drivers get a car slightly moving then waste time changing gear while they're in a position of relative danger.
I think the problem is that pupils are not encouraged to accelerate briskly, with the consequence that they are not building up enough speed, there for holding on to first gear for too long. When entering a roundabout from a standstill, if you accelerate briskly on to the roundabout there is a point where the steering is set slightly left, and for a moment, no further steering is required. It's at this point where second gear is taken before steering back to the right. Some learners change gear as you said, when the car is just moving. If they are not encouraged to use brisk acceleration (relatively) they will struggle. Years ago I had an associate who was still going around roundabouts in first gear even after four years of driving.
I cure any pupil who is affraid to us the revs by taking them up Spread Eagle Hill on the C13 just south of Melbury Abbas between Shaftesbury and Blandford Forum. This is a 1:6 hill, which may be known to those who have attended the Shaftesbuy Driving Days. If they do not get going they will end up not getting above about 20mph, especially if they change up to third before the revs have hit 5000rpm in my 1.4 Fiesta.
