Reading this thread, SP, your example immediately came to mind, even before I checked the Google maps link.
It's fairly local to me and I've had the pleasure of driving round that particular roundabout (North Orbital London Colney roundabout, for those who don't know) a couple of times recently.
Most drivers - I suspect the ones who know and use the route frequently - get it right. A few are totally bemused by the whole thing and flounder slowly round, realising they're in the wrong lane at some point.
A few, as has been said above, couldn't give a toss and use whichever lane happens to be free, assuming they can just change willy-nilly later on. If they happen to be alongside a 50-tonne artic at the crucial point that can cause problems.
