Dealing with Vehicles opposite at a Crossroads

[foxtrotmike]

Can I have some guidance on how to deal with, when waiting at a crossroads, with vehicles also waiting on the opposite side junction.

Street View Example Link, the camera is positioned where my vehicle would be waiting to give way (on the line)

I wish to turn right in this example and the vehicle opposite wishes to go straight on (but you could argue the scenario would be similar if they were turning left.

There is the danger here of both of us emerging at the same time and colliding, particularly as this has to be done swiftly for the density of traffic.

Any ideas how this could be done

The issue here was not so much who had right of way but when to assert yourself to go, in the situation I had that when you had a gap, it wasn't very big to play about with and had to go, and a situation where you might need to start going just before the last vehicle from the right has passed you

I would have had the same question if the other vehicle instead was turning left.

To give another example, I had a similar situation a while back at the junction below, This time it was a tractor waiting in the central reservation to cross over, which i didn't want to argue with.
