crashed in Taipo yesterday (at a spot where I've crossed the road hundreds of times) to free victims trapped underneath.
This is far from the first such case in Hong Kong. Years ago I helped to lift a car that knocked down a young boy in North Point. Meanwhile it has been widely reported that in mainland China, most people will steer well clear of helping accident (or worse) victims rather than get involved in potentially messy consequences.
There would be scope for an interesting master's thesis on why mutual aid thrives in a supposedly competitive capitalist society while being conspicuously absent in a supposedly collectivist one. Suffice it to say here that "one country, two systems" is not just about politica and economics.
