I come from mainland Europe where we drive on the right, and I was in the UK couple of months ago, and was forced (due to the volcano) to drive from London to Glasgow. At first it was all really wired and scary, but once I drove off the rent-a-car parking lot onto a road where there ware other cars it was easy. My point is that other cars help you if you "suddenly" have to drive on the other side of the road. I did, however, drove a car with the steering wheel on the right side, so that might help (unlike here where the driver sits at the edge of the road).
