the road has two lanes, one for straight, one for left turn, and some space for bicycles and motorcycles. during rush hour, the road is packed with three lines of cars, that's fine. even with that, some drivers still want to cut in between lanes. this is my experience this morning. i was driving as a good citizen to work this morning. the road was jammed with traffic, as usual. a van wanted to merge in the traffic, nobody yielded. the two cars almost collided. i let the van in. from nowhere, a taxi popped up and joined in. now the traffic was jammed. i waited these 2 cars mingled. after the traffic was just back to normal, a 3rd car tried to cut in. now i was totally pissed off, and pushed that car behind, like other drivers did.
