I’ve been trying to make a scale model so that I can get a better understanding of how the trailer reacts to the tractor. (But this is not as easy as it sounds… most toy lorries have fixed front wheels… any ideas?).
The remote control ones are good but get one that will move slowly.

More the reason for you going off banging your drum with the powers that be and making the test more realistic
A breath of fresh air, if only driving tests reflected the real world.
The training and tests could but who will be prepared to pay for the extra time on training and for a longer test
I reckon that it would probably take about 4 weeks of total training taken over a longer period and 2 hours of testing probably done in two parts - one as now and a second fully loaded with realistic on the road reversing.
I learnt to drive in a farm tractor like the Poles.
I had a Corgi diecast model of a Ford 5000 with a single axle Weeks tipping trailer but the tractor had a steering axle and an automatic pick up hitch
Ford 5000 Super Major Farm Tractor by Corgi from 1967.
This lovely Tractor model was finished in blue, grey and white, with controlled steering and lifting mechanism,
THIS LINK may help , download the demo and you can have a go at super 'B’s too, gives you an idea of the principals involved.
I read somewhere (probably one of Rog’s posts) that when reversing in a straight line, if theres more trailer in one mirror then turn the wheel towards that mirror.

ROG: Straight line reverse — if the trailer starts to go into one of the mirrors then turn the wheel into that mirror until both mirrors are seeing the same amount of trailer again, then keep the mirrors seeing the same amount each. To make the trailer go to the left or right — slightly pull the wheel the opposite way to what you want the trailer to go which will put a little more trailer in the mirror on the side you want it to go and hold that little amount for a few seconds by slight adjustments to the wheel.
To stop the bending and to find out exactly where you now are, turn the wheel into the mirror that has the trailer in it until both mirrors see the same amount of trailer. The bending of the trailer will not stop until both mirrors are seeing the same amount of trailer.
This straight line reversing and the slight moving to adjust position of the trailer gives the trainees the basic information.
Only been driving class 1 since last october found reversing hard at first but like most say take your time. i do tend to oversteer alot but i’m getting there. i’m now playing with 10mtr and 8mtr rear steer trailers how much fun are they, brings a whole new concept but i’ve got the hang of them now
Just to throw in a different subjective approach that might work (make sense) for some people.
Think of the Drive Axle wheels as the ‘steering’ wheels of a rigid. In the case of a Rigid. It is the angle of those wheels that will determine the direction in which the rear of the vehicle will follow.
Determine the desired angle (offset) that you wish to achieve, and then use the ‘steered’ axle of the unit to achieve that angle at the Drive axle.
It is a method of breaking the ‘geometric’ components down into separate activities and considering each in turn.
It is an approach that would probably be more useful for someone with a knowledge of mechanics (or an understanding of ‘levers’) or with an analytical mindset.
For some, to express it those terms would probably ‘blow their brains’. For others, it just might be the catalyst that puts everything into perspective.

Agree entirely with all of that Ken, in fact it is the way (with appropriate changes of course) that I taught myself and all my other drawbar drivers how to reverse those. Not everyone can get their heads round the concept though.
Best advice i got was don’t look at shunters and try to copy them
Basically shunters reverse all day long know their vehicle and yard inside out so just basically one big sharp movement chuck it in a bay.
Lots of newbies try that kinda approach one big huge movement will get it where its going, when in reality its short constant adjustments will get it going correctly.
