Lane selection at this roundabout

[skahigh]

This is really doing my head in now, every morning I come around this roundabout in Cardiff approaching from point A on the map below and leaving at point B. I am always in the far right lane indicating right and switching to a left indication when about level (or ever-so-slightly after) with the exit prior to the one I want to take. Every day without fail someone takes up position in the lane to my left and comes all the way around the roundabout with me either taking the same exit as me or one further around the roundabout.

As I'm on the motorbike this makes me a little vulnerable when trying to move across to the outside lane and leave the roundabout and it's extremely frustrating.

Is it me? Am I in the wrong? If not, why does everybody take up the wrong lane here? It's not that hard to understand is it???

Do you mean point "C" or point "D" below?

C

There's a motorbike-length gap in front of them, I take it? Make sure you're next to that gap, not next to the car, and accelerate into the gap and down your exit.

Oh I do but, turning right and looking over your left shoulder almost 180 degrees behind you (due to the bend) to check it's safe in the dark and wet with raindrops all over your visor isn't the most pleasant of experiences and does make you feel vulnerable.

Thanks for the validation chaps, I will continue as I am doing.

It seems to me that the roundabout is quite clearly marked, the only real problem with the markings in my view is that they don't lead you off at each exit in turn.

So, presumably it's vehicles leaving the southbound A470 & joining the roundabout who are moving up your nearside?

You mean those leaving the A470 and joining the roundabout at D?

If so, no, there are three lanes of traffic there and they are always pushing out to try and get on to the roundabout (often not noticing motorcycles coming around the roundabout with indicators on), they are just an extra hazard to watch out for.

It's traffic joining the roundabout at the same time as me from the North/East bound A470 at point A that are the problem.

No - I meant the traffic leaving the southbound A470 & joining the roundabout between "A" and "C".

Whoops, mixed up my own roads.

Those joining from the A470 can be a problem if they pull out inappropriately but that doesn't usually happen as there is two vehicles coming towards them around the roundabout.

The left of the two lanes entering the roundabout (ignoring the slip lane on the left) is marked with an arrow on the ground indicating straight ahead, the junction I am taking is almost 270 degrees around the roundabout. That surely can't be considered straight ahead?
