- the stupid - stupid idea of having one lane split into two lanes at a traffic light with both lanes going through the intersection then getting back to one lane. If there is ANY logical explanation to that I am really keen to hear it. But I do not believe there is any.
It's quite simple really. The light turns green for ~15secs, You can get twice as many cars through the intersection in the same amount of time as you could if there was only 1 lane at the lights. When people take off from lights a gap opens up, which is large enough for the two lanes to merge once they've gone through the lights.
Trust me, if there was only 1 lane through the lights, your journey would take more time than if there were 2 lanes merging back to 1 lane.
