Because it's caused a lot of bickering and i drive over it twice a day and regularly have near misses. And it makes a change from parking 
You're approaching this roundabout. There are 4 exits, and you're taking exit 2 which is at 11 on a clock (I marked the exit with a red arrow)
Which lane would you use?
There is a sign for the roundabout as you approach which just shows the exits and doesn't state left turn only or anything vaguely relating to exits
