I ride round such bends well out in the road, but vigilant and ready to dive to the left if I am unlucky enough to encounter a lunatic overtaker coming straight at me.
It's not just overtakers though ...
I had a car come round a bend straight at me because the driver was busy looking at magnificent scenery to his left.
I worry about meeting a tourist coming the other way who had forgotten that we drive on the left (a friend on holiday in Spain forgot that they drive on the right and descended a mountain on the left
).
Then there is plain stupidity ... There is a very fast descent in Hebden Bridge down to a very tight LH bend (Birchcliffe Road).

One impatient driver decided to save time by cutting across the bend directly in front of me. I was far enough out in the road to spot him doing it and was able to dive into the small gap that he had left me, missing the side of his car by inches.
