Managed to spin 270 degrees setting up to exit a roundabout at about 15-
20mph.Must have been diesel as my tyres are all still decent, but it felt like I had just stepped onto sheet ice, the front went a bit light, then trc went mental as I pirouetted gracefully round avoiding all sorts of cars, cheap and not so, and ended up facing the wrong way, almost sideways on, on a high planted roundabout, so no-one coming round could see me waiting for them.
Had to wait the best part of 5 minutes before someone helped me out by stopping and putting their hazards on, instead of just going round me slowly and blocking my possible exit routes.
And no, I'm not posting this in uk.rec.driving so the sanctimonious IAM crowd can crow.
