OI can't see any issue with the driver in the left lane at all. It's not compulsory to exit if you are in the left lane. The car in the right hand is clearly a chump.
Hwc 186
When taking an exit to the right or going full circle (unless signs or markings indicate otherwise):
Signal right and approach the exit in the right hand lane
Keep to the right on the roundabout until you need to change lanes to reach your exit
Signal left after you have passed the exit before the one you intend to take
When taking any intermediate exit (unless signs or markings indicate otherwise):
Select the appropriate lane on approach to the roundabout
Stay in the lane until you need to alter your lane to exit
Signal left after you have passed the exit before the one you want to take
