We have a similar situation here, not caused by a tunnel but people parking end to end, in the road, so there is no gap to dive into to avoid on coming tragic, as its a slow right hander with hedges on the right hand side,
as you approach a major-ish road your view is restricted somewhat, but the people coming off the road, its a left hand bend, with the parked cars on their off side, and they have a much better view.
But they will still insist in proceeding to face of on coming traffic as its their "priority". Even though going the other way, you are "committed" and have no where to go.
