There is a very narrow bridge near here, leading to one of the villages, and I would not live there if you paid me, I would have ulcers.
The approach road in both directions turns a right angle in a dip to go over the bridge (it should have traffic lights really) and it is perfectly possible if 2 cars are just in each other's blind spot for them both to land on the bridge at about the same time....
2 problems - if you get a stupid old git like jude's he will not back off, even if you were halfway across when he got there, and even if there is another car behind you; and if 2 of you arrive at about the same time, the one who does back off is then completely unable to tell if anything else is coming - I have done the approach-and-back-off as many as 3 times in a row.
Grrrrr.
Agree with pretty much everything on here already. "You could get a bleeding bus through there!" is one of my choicer phrases. There are a lot of divvy old drivers round here who don't know who has right of way at roundabouts, and will not turn right off a main road until there is nothing coming the other way. I know it's better to be safe than sorry but honestly, if they really can't tell how fast an oncoming car is going they shouldn't be driving.
Oh, and people waiting to turn right who don't even put their car into gear, apparently, until the oncoming car is already past.
People who don't indicate on roundabouts, especially.
Men who hate being overtaken by a woman and have to overtake back ASAP.
