As I trip over the piles of rubbish that adorn our streets, I wonder whether they are piled there by refuse operatives, who will be back later in the van to do a quick scoop up, or whether it is an extension of the litter lemming phenomenon, whereby when somebody dumps something, it seems to be carte blanche for others to follow suit. Either way, I feel sorry for the Maserati driver and wonder how he extricated himself from the space without having to drive over all those bags.
