Taipei traffic light change duration too short ?

Always had a feeling that trffice light change too fast. Recently driving the car I felt it is getting even shorter. There is an article here HERE with some information. Even there is no rule, some say that it should be 1 second per 10 mile/hours for yellow to red. That would mean about 3 seconds. but in Taipei the time is often about 2.5 seconds from green to red ! It almost gives drivers no choice between stopping or keep driving because often the distance is not enough to safely break. Then not even talk about the time for bikers. So when you bike, follow the pedestrian traffic lights and not the ones for cars.
