Glad to see you getting into the spirit of BMW driving. However the most important point to make concerns joining and exiting motorways. When joining the motorway accelerate flat out along the slip lane so that you can shoot straight across to lane 3 [lanes 1 and 2 do not apply to BMW's & Merc's]. When leaving the motorway the opposite applies using the left hand indicators as an art form of arrogance. Happy motoring & note how other drivers will welcome your moves with friendly waving jestures and playful hooting of their horns.
However, no mention of this is made in the Highway Code...
