On the Tsing Kwai Highway heading towards Lantau Island, as you approach Tsing Yi, you pass beneath a couple of large electronic road signs that were, presumably, designed to warn of problem conditions ahead; poor visibility or a crash, perhaps.
When they are not employed in their primary task - in other words, most of the time - instead of being turned off, they display arguably useful messages such as 'Don't drink and drive' and 'Change lanes carefully'. Sometimes, though, the message is, 'Zero road accidents: HK's goal'. Why?
Are there people on our roads who think that the government or people of Hong Kong would prefer a few accidents to none at all? Or many, even? Would someone like that drive more carefully if they were informed otherwise?
Or was it the case that someone in the Highways Department needed to put their hand up when 'good ideas' were being asked for?
For the record, making drivers take their eyes off the road to take in information of no value whatsoever is the very opposite of a good idea.
