In the UK deep in the countryside there are miles and miles of twisty single track roads. In Cornwall in particular they have high walled sides for some reason, and are just wide enough to drive down. All the time you are praying - please don't let there be someone coming the other way. But they do. As you were driving you took note of occasional deliberate passing places but also entrances to fields which would also do. Coming face to face with another car, one of you decides there was a passing place not so far back and reverses back 100 yards (now the prayer is please don't let there be someone following me). You reverse in, the other driver smiles and thanks you and you go on your way. I think that will need a level 6.
