　　Many Chinese have been greatly shocked by the traffic accident caused by the drunk driver Sun Weiming，who has killed five and injured some others in Chengdu，Sichuan.However，such a case is not rare.

　　Today，traffic accidents may have been regarded as a social problem.The car has killed and disabled more people in its brief history than any bomb or weapon ever invented.Much of the blood on the street flows actually from rude behavior of drivers who refuse to respect the legal and moral rights of others.In fact，the enemies of society on wheels are rather harmless but just ordinary people acting carelessly，you might say.But it is a principle both of law and common morality that carelessness is no excuse when one’s actions could bring death or damage to others.A minority of the killers go even far beyond carelessness that can be imagined.
