阅读下面的短文，然后用大约 =30个词概括其内容要点。
The motor vehicle 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 basically from careless behavior of drivers who refuse to
respect the legal and moral rights of others. So the killing on the road may be regarded as a social problem.
In fact, the enemies of society on wheels are rather harmless people, just ordinary people acting carelessly,
you might say. But carelessness is no excuse when one's actions could bring death or damage to others.
Researchers have estimated that as many as 80 percent of all automobile accidents are caused due to the
psychological condition of the driver. Emotional upsets can slow drivers' judgments and reactions, and blind
them to dangers that might otherwise be obvious. The experts wam that it is important for every driver to
make an effort to keep one's emotions under control.
Yet drivers are not the only people to blame for road accidents. Street walkers regularly break traffic
regulations. They are at fault in most vehicle walker accidents and many cyclists even be- lieve that they need
not follow the basic rules of the road.
