Near miss today. There was a car approaching the mini roundabout from the right but he was a while off and wasn’t near the line yet so I entered the roundabout as I had time. However he sped up very very fast to intimidate me. He was so close going to the side of me. I do know it’s give way to the right but I thought as I’d already entered before him and I was already on the roundabout and he was not yet entering then I thought I would have had the right of way?
