You're going along a road, there is a van or perhaps there are several vehivles parked on the the other side. You're in primary position, or at the very least you're not in the gutter. Car coming the other way pulls out from behind the parked vehicles (thus on to the wrong side of the road) and drives straight at you; clearly you should have priority on your side of the road, but the other guy expects you to disappear somewhere. I'm sure this happens to other people too! What do you do?
