Consider the question: Why do drivers in Hong Kong speed up to a red traffic light?

Having driven in Hong Kong for over a year, I have seen so many drivers speed up and then slam on their brakes towards a "red light".

Drivers who exhibit this habit the most are taxi and mini-bus drivers. You would think that of all people, taxi drivers would have the most to gain if they approached a red light progressively. It would save them gas and lessen the wear on the brakes of their cars.

So, is this just another phenomenon of Hong Kong's bustling life style?
