I have little issue with the turret view or the instant 'transfer'.
The turret view can easily be explained as the ship using its sensors to generate a full 360 degree image of everything around it. It can then insert a 3D view of itself (as was mentioned in the stream so that you can stay orientated) and there you are. Actually something similar was done years ago in one of the follow-up titles about the Rangers. In that the fire control was done using a holographic chamber where the gunner floated in the middle and used her arms to fire the ships weapons. Was very impressive and a brilliant solution to controlling the weapons on a ship where the attacks can come from anywhere.
The instant transfer is simply teleprescence. In one of the books it was said there is hyperspace communications and that can be used to send the data around at FTL speeds.
Both explanations work for me and how I make them integrate into the Elite universe. They are consistent and believable to me so do not upset my immersion in the game
