yea, fair point on the video, not really an expert in this stuff. It would have shown the speeds involved and that I had to jam on the brakes and that he then then stopped and blocked the exit (the lorry was stationary).
Ah, but your mistake was thinking that a BMW driver (even driving an old beat-up one) would actually stop, roundabout or not! He's now moving onto tailgating the pickup in front no doubt.
Best driver every to walk the face of the earth, would trust him with my life! And his car is awesome!
