I was driving over the Bealach na Ba pass the other day going uphill when a motorhome and a car behind it came the other way.
There was a passing place on my right, but not big enough for the car and motorhome so I pulled into it to let them by. (Wrong I know, I should have stopped adjacent to the layby whilst they tried to manouvre past through the layby, but it was tight and I thought this would be easier).
The motorhome (German) stopped and the driver folded his arms and refused to go any further. I beckoned and signalled that they would clear me by about 2 feet but still he refused to go.
Eventually the driver of the car got out, walked to the front of the motorhome and showed him that he had a clear route through and gently explained that it might be in his best interests to take it which he did.
The car driver looked at me, looked at the now moving motorhome and gave what looked to me to be some sort of waving gesture in his direction. Must be some sort of Scottish custom?
