In reply to Simon: It is a shame that so many of our mighty road warriors have to sublimate their instincts by travelling a puny 100km/h.
And why should they use indicators or not tailgate mere mortals in inferior vehicles struggling to make the required limit.
Especially when you consider their mighty steeds, equipped with ramming bars and ridiculously over- powered engines could easily ram the detritus off the road.
Naturally they should be allowed right of way on all roundabouts at any stage and the mandatory 1½ car park spaces. I am amazed and awed by the sheer restraint of such drivers.
