Over the time I’ve had a hell of a lot of lefthanders of different makes, on one or two firms I had the job of taking new drivers out to show them the ropes with lefthanders, you just try sitting in the right hand seat of a left ■■■■■■ without a steering wheel, shouting get over, get over, talk about a brown pants job, my only advise, as has been said take you time it will come to you, driving in the UK make shore the offside mirror is set up right so you can see the white centre line and drive to that and stay inside it, keep pulling the motor towards the kerb you wont hit the lamp posts, good luck…
One top tip passed on to me by a (now sadly deceased) friend was that in order to practice road positioning in a LHD vehicle is to reverse your car through your local town at 30mph. This gives the perspective of driving a LHD vehicle in a real world scenario.
