It's a pet peeve of mine too. It's so annoying to try driving on a motorway or dual carriageway and see someone hogging the fast lane. There definitely needs to be a publicity campaign to teach people how to drive on a motorway/ dual carraigeway properly.
I drive on the right hand lane. Now I do it at speed, and if there is something behind me that is driving up my hole I will pull into the left or if there is no car in the left hand lane that will slow me down I will drive in the left. But other than that it is mainly right
Sorry, but you are not using the road correctly. You are supposed to stay left
and only use the right lane for overtaking purposes.
And don't get me started about motorways with 3 lanes either side - Irish drivers haven't a clue how to use those.
