Killer roundabout

Could this be the most dangerous roundabout in the UK?

I have come across cyclists, motorcycles and cars in the centre of this roundabout when it was grass and bushes. Now there is a cheese grater waiting to slice up the next victim.

It can be found at the junction of the A484 and the B4297.

This at the end of the bridge over the river Loughor close to Llanelli South Wales.
