Yeah, I think a diagram needs to go with it in order to make sense. I can't draw though, here's an attempt.


Ok lets say you are in the left lane.....u can only exit on the top and on the left....right lane can do the right exit and the top...but silly people in the right lane go all the way to the left exit....

so lets say i want to exit on the top one and im on the left lane going into round about and silly person next to me is in right lane but wants to exit on the left exit i can't exit cuz they are silly....

i hope you are less dazed now....but i know it's not a very good explanation or picture....excuse me i just drove 2 hours in traffic =/

 

There are lots of roundabouts where I live in London you give way to cars coming from the right, might be left over where you are and if you’re already on the roundabout you have right of way.
