When someone was warned, he was angry and obstinately chased and overtook, finally stopping the car and making an argument or fist fight on the street and colliding with a car that came later, many cases of death or injury by such accident is reported. When I tried to stop the car on the way in front of my relatives' house, I was scolded by a driver shouting "Is there a fool to stop the car in such a place?" and my car was kicked by him. I apologized as "I am sorry," but probably it was a big fight if his opponent was not me, and someone might be killed. People who shout and rush around are not necessarily those of organized crime groups but also of ordinary humans. I think that a driver becomes arrogant and yelling and chasing because the driver think himself as a great person as he is able to move the vehicle with the engine with his will. I think the cars are demons. About license renewal, now the elderly is sieved by the dementia test, I think that the license center should not give a license to the persons who are soon angered or arrogant by conducting personality test at the stage of license acquisition.
