How about this for a new steering technique, then:
A couple of days ago I was driving from the top of Kirkstone pass, down to Ambleside, this being a long steep hill, with a fair few sharp bends and quite narrow in parts: locally it is known as 'The Struggle.'
Now then, I was driving down a section of this road using only my right hand for steering. The reason for this will remain unexplained.
Anyhow, when I came to a sharp LH bend I started out with my right hand at about 3 on the SW and I began to apply some left lock. My hand got round to about 8, at which point I realised that more lock would be needed. OK, no problem: all it needed was to grip the rim with RH thumb and forefinger, pivot my other three fingers around this grip point so that they then held the wheel rim from the inside. The forefinger then joined them on the inside of the rim, and the thumb adopted a slightly adjusted position on the face of the SW rim. While this was going on my hand moved round to about 5, which I could not have achieved using fixed grip!
This was an entirely unplanned form of steering, and TBH it quite surprised me when I realised what I had done. Even so, for an unhurried manoeuvre at about 20-25 mph it actually gave a quite decent result.
I suppose the point I'm trying to make is that when you have a (long established) wide variety of steering wheel handling methods, you can be pretty sure that there will be something available that will get the job done, even if some would say it's not what they would want to see on an advanced test; or at all, for that matter!
