That isn't practical at intersections like Greenlane East and Great South Road. Each lane has an arrow indicating what direction is acceptable...and in one case there are two RH turn lanes. But if you only go in the leftward lane of the two, you're clogging the lane that wants to go onto the motorway northbound...and impeding your own progress if you want to be in right lane after the turn to proceed through the roundabout and onward toward Remuera. People who know the intersection stay left for the motorway and right to avoid the motorway and cross it instead.....along with the usual twats who slow EVERYONE down (including themselves) by queueing on the right and then try to cut in to the queue on the left for the on-ramp. Their tyres should go instantly flat for being idiots.
Its amazing how easy it is to miss those people who are in the wrong lane trying to push in at the front of the queue when you are busy sorting out the coin collection in the ash tray or trying to alphabatize the presets on the stereo. Shame that sometimes they cant get in and end up having to go all the way around the roundabout and join the other queue of people.
