Today's Vietnamese society, no one is unfamiliar with traffic jams. Firstly, over time it became a familiar image, which is inevitable every day and no one has come up with a solution to completely solve this problem. Secondly, at rush hour around 4-5 pm, when you go out on the street, you will have a terrible headache because of the horns emanating from thousands of motorbikes, hundreds of cars and many other vehicles. The wide road bed seemed to become overloaded, unable to accommodate people and vehicles participating in traffic, so people and cars just calmly galloped straight onto the sidewalk, then followed each other down without any problems. I didn't know it or care that what I had just done started a new traffic jam. Thirdly, at every intersection, every turn, the traffic lights seem to be disabled, even when there are policemen standing by to show the way and control the vehicle to solve the traffic jam, there are still motorbikes hitting the road. from one side to the other, what an uncultured and ignorant behavior? Finally Cars go sideways, cars go along, cars go down, cars go in reverse, every car emits a loud whistle, feeling on the road at that time was a battlefield of ferocious beasts, ready to rush into each other, Ignore all traffic safety regulations for your own purposes only.
