Yeah that ****es me off as well haha. Taking a right turn half way down a dual carriageway DOES NOT mean you can sit in the right lane at 30 - 40mph for 5 mins!Nah if the lanes are directional then its a different story, thats just nobbish.
It works the other way around too, there's a few dual carriageway type roads around here that are a few hundred yards long with roundabouts and directional lanes at the end. It really pees me off when someone pootles along at 30 in the right hand lane all the way down because they're turning right at the end...
