I understand that a circle isn’t the most natural of obstacles to encounter when cruising along, but the logistics involved are really quite simple; get in the right fucking lane you tit.
If there’s two lanes, only use the right one to turn right. That’s the third exit on most “domestic” roundabouts you’re likely to encounter in this bloody country. Just because there’s a queue to go straight ahead, it doesn’t mean you can cheat.
Deal with it.
The next time I have chastise a fellow driver in my own head, without actually gesturing or showing my frustration in any way due to over-politeness and a fear of conflict, they might not be so lucky.
