This morning at a busy time at one of those multiple traffic lights junctions.
The roundabout has 3 exits. As I approached there's a car A stopped on the roundabout, car B waiting at it's give way line to the right, 2 cars in front of me. The road to my left has a zebra crossing and it's not moving. 2 cars in front of me go behind car A over the middle of the roundabout to take the 2nd exit. I also need the 2nd exit but the first lane traffic starts moving slowly so as car A is leaving the roundabout entre the roundabout to go to the 2nd exit which is clear. Car B is also moving, but his exit is not clear, so allthough he has right of way, I take it so I'm not blocked but get beeped.
Aibu, I didn't have right of way, should have let the cars to the right keep crawling in front of me. Ainbu, car B had no right to go on the roundabout before the exit was clear.
