I personally think that one of the key benefits of the primary position is visibility. It places you firmly in the drivers field of view. I feel that the further left you are the more likely you are to fall into peripheral vision of the following drivers and out of mind.
I totally agree though that awareness is important and in the case of the cyclist in the video I posted he didn't look around when he rejoined the road. I'm not sure he knew where the following car was. (we need a disapproving emoticon!)
