Another point: if you're on your own and not overtaking someone on such a road, where should you position yourself? To the extreme left, say less than 1m away from the verge (as if it were normal witdh single carriageway), leaving a second virtual overtaking lane to your immediate right, but still on "your side" of the carriageway?

Or should you be more "centre-left", i.e. the left hand side of your vehicle should be about 1/3 of the way across your lane? In which case, an overtaking vehicle may have to straddle over to the other side of the road?

I ask this point because it's very relevant for motorcyclists: when learning motorcycling, you are instructed to be "centre-left" of the carriageway. So if you're on a normal width road, where, for argument's sake, we'll assume the road width is 6m, so 2x 3m, then you'd be about 1m to 1m50 away from the verge.

Now if you "stretch" your vehicle and road's width proportionally to have a much wider but still single carriageway road like the OP mentioned, your side of the carriageway is now, say, 7m wide.

Where do you position yourself now? When on a bike, I'd still be centre-left, i.e. 2m to 3.5m away from the verge. But if you do the same thing in a car, you will not leave a car's width free space to your right allowing others to overtake without straddling over the middle of the road.

If I'm in a car, I'd still drive centre-left, but if someone travelling super fast were to come up behind me, I would pull over a bit more giving him room to overtake whilst still remaining on my side of the road.

What's the expected behaviour ?

The correct road position for normal driving in a car is 1m from the kerb on a wide road or the middle of your lane on a narrow road. So if the lane is wide enough for more than 1 car you should be 1m from the kerb.

For a motorbike you position where the driver would be sat in a car.

If you are going to move road position for any advanced driving antics you need to check your mirrors first for overtaking traffic.
