Letters to the Editor, November 29, 2012
I refer to the letter by Sai Pradhan ("Weak law on idling engine ban is proving impossible to enforce", November 26). I totally agree that the Statutory Ban Against Idling of Motor Vehicle Engines is a pitiful piece of legislation that has made a laughing stock of the transport and environmental protection departments.

Your correspondent appeals to drivers to "do the right thing", but we live in an extremely selfish city and such an appeal is bound to fall on deaf ears.
However, there is a well-known resident of Tsim Sha Tsui who has a much more direct way of addressing smug, obstinate and inconsiderate drivers. This lady carries an A4-size sign in Chinese characters that makes it absolutely clear to any driver that she does not appreciate their idling fumes. She brandishes this sign until they switch off.
She may be "five foot two and eyes of blue" but her fortitude is remarkably effective: even the surliest drivers submit.
The police, traffic wardens and environmental protection inspectors have shown themselves to be impotent on this matter, and citizens who value their lungs should take similar vigilante action.
