Or you could have just moved to the middle lane, let him past, and resumed your overtake. Space to do so, would have left you in a safer position? These issues are normally caused by 2 people, not one.
When taking the first exit (unless signs and markings indicate otherwise):
Signal left and approach the exit in the left hand lane
Keep to the left on the roundabout and signal left to leave
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
and theres the issue with overtaking cyclists properly. Time it as badly as that, you hit head on traffic, which for some weird reason, is coming at you constantly on every road, at every hour of the day, in the country. If there wasnt any traffic coming the other way, this would simply be a van overtaking a cyclist with a good amount of space.
WTF is up with his nose???
