有人认为社会公众需要什么，政府就要无条件的提供，你怎么看

  Driving while talking on a hand-held mobile phone has long been considered a danger. But even drivers who use hands free devices are a nuisance – because they are slowing everyone else down, according to a study.

David Strayer, a psychology professor in Utah University’s traffic lab, conducted a study involving 36 university students driving on motorways. Each used a hands free phone for half the trip but not for the other half. The students were told to obey posted speed limits and use turn signals but the rest of the driving decisions were up to them . What Strayer found is that when the drivers were distracted（使分心）by a phone conversation , they made fewer lane（车道） changes, drove slower and took longer to get where they were going. Fellow researcher Professor Peter Martin, who teaches civil and environmental engineering at Utat University, said,“Ordinarily a slower driver should be safer ， but that’s not the case when people are talking on a cell phone.”

In general , drivers who used mobile phones while driving took three percent longer to drive along the same high-density route than drivers who didn’t. When stuck behind a dawdling(磨蹭的) driver , it took them between 25 and 50 seconds longer to switch to an open lane to overtake. Those delays can add up when you consider studies that suggest as many as 10 percent of US drivers are using a cell phone at any one time. And delays in traffic streams of very small amounts can grow into massively when drivers are crossing a  highway.” Our next step is to use computer models to determine just how much those delays are costing drivers in time and in extra fuel costs,” Martrin said.
