Right of way question

I have a driving question for anyone that would consider themselves a pro 🤣 My driving test is next week, and this one particular road examiners love gives me the shudders.

Essentially its a long ass narrow road thats 99% of the time rammed with cars on the left, so only one car can go through at a time. obviously, if I’m approaching from the view shown, I have to give way to the traffic oncoming.

However, it is such a long road, which also bends at the end. Whenever i come here, I always stop and go into first gear and have a good look to see if anyones coming. However, a lot of people tend to absolutely fly down here from the other side and obviously as the road bends, if they come at speed, its unlikely you will see them until you’ve already committed.

I have been down this road before, and checked to see nobody was coming when I committed, but a lot of the time instead of giving way as I’ve already committed, they continue hurtling at you even if you’re halfway down the road lol.

My question is on a test, if I had already committed, and there is physically nowhere for me to pull in (which is quite often the case with this road), would it be a fail if the oncoming vehicle had to reverse??? Obviously if there was somewhere to pull in i would, but I’ve had people on this road before (usually van drivers lol) wind up their window and start yelling about their right of way.
