Oncoming drivers failing to give way.

[FreeLitres]

Hypothetical situation;

You are on a long straight road only wide enough for one vehicle in each direction. Ahead, there is an obstruction on the other side of the road such as a bus picking up a long line of passengers. As you approach from some distance away, you can see a line of cars starting to overtake the bus as expected. However, as you get closer, the oncoming cars are still passing the bus and now you are almost level with the bus and they are still coming, blocking your side of the road so you have to stop.

If the oncoming cars just keep coming, what do you do?

Same story when you are approaching a traffic calming bottleneck and the oncoming cars have this sign



So its your right of way but one car comes through and makes you stop, then a second, then a third.

Has anyone ever just got frustrated and driven forward to make them reverse?
