Confusingly, the slow lane is called the "inside lane" in the UK, even though it's on the edge of the road and the fast lanes are in the middle.
That used to be the case in Ireland too, but confusion due to cultural contamination means pretty much everyone moved to numbering lanes (from the "outside"/"slow"/leftmost lane).
