rude driving.On the other hand，a little politeness goes a long way towards reducing the possibility of quarrelling and fighting.A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and becomes so necessary in modern traffic conditions.But such behavior of politeness is by no means enough.Many drivers nowadays don't even seem able to recognize politeness when they see it.

　　However，misplaced politeness can also be dangerous.A typical example is the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may not be able to stop in time.The same goes for encouraging old ladies to cross the road wherever and whenever they want to.

　　An experienced driver，whose manners are faultless，told me it would help if drivers learnt to correctly join in a traffic stream without causing total blockages that give rise to unpleasant feelings. Unfortunately，modern drivers can't even learn to drive，let alone master the roadmanship (公路驾车技能)．Years ago，experts warned us that the fast increase of the car ownership would demand more give­and­take (互谅互让) from all road users.It is high time for all of us to take this message to heart.
