you position yourself in the middle of the road, or in the right hand half of the road purely for the purposes of preventing a driver from overtaking you.
Cyclists position themselves towards the right of the lane if they need to turn right across on coming traffic or switch lanes. This is the best way to altert the traffic behind of their intentions and gives room to undertake also if necessary.
Being in the centre of a lane is the safest/most visible place to be. Most cyclists would stick slightly to the left unless they feel vulnerable for reason, like when their is debris and potholes in the road. Parked cars on the left etc.
Also importantly on roundabouts to actually prevent overtaking and maximise visibility. As overtaking cyclists on roundabouts is super hazardous, sticking to the left of a lane encourages this practice. It also leaves the cyclists very vulnerable to a common practice of the cars turning left to exit the roundabout right through the path of the cyclist. Any cyclists would be insane not to use the "primary" position when going around a roundabout.
Also on a regular road when a cyclist needs to turn left, they often take the centre position prior to the turn and maintain it for the turn to prevent getting sandwiched in to the gap by cars thinking they can squeeze round. It also prevents getting stuck in the blindspots of large vehicles and getting squished by them.
Lastly, if a cyclist is doing a decent speed. Then they have every right to be bang smack in the middle all day long. Car drivers seem to be ok with mopeds riding in the middle of the road even though they top out at about 25mph. All cyclists can manage 30mph downhill, and if they are going fast then it really is much safer for them to be in the middle even without any external factors, just handling and negotiation road surface etc.
