汽车引擎会太安静吗?就混合动力汽车而言,那些安静的发动机可能构成无法预料的风险因为他们太安静了,行人会听到。闲置的混合动力从没有听到引擎咆哮的车道和行人中撤出,继续走进汽车的路。我认为噪声污染的减少(例如减少空气污染)将被认为是该技术的好处。(我知道我想在纽约这里安静的街道。)但是我从未考虑过安静的杂种。
unforeseen risk because they are too quiet to be heard by pedestrians. Idling hybrids pull out of driveways and pedestrians, who don’t hear the roar of an engine, continue walking into the car’s path. I would think the reduction in noise pollution (like the lessening of air pollution) would be considered a benefit of the technology. ">
