CALMING?

Yet another traffic obstruction has appeared in Great Hollands – a traffic ‘calming’ chicane. This, I understand is to prevent the recent near misses when vehicles emerging from a side street cannot be seen because of an overgrown Pyrocanthus bush. Would cutting back the bush be cheaper and more effective? I note the recent skid marks that have appeared on both sides of the obstruction!
So, following the same logic, if you put a rubber duck beside the site of a recent accident and there was not another accident there for a while, one could claim that the rubber duck was responsible for the improved safety!
