問題詳情

Today the car seems to make periodic leaps in progress. A variety of driver assistance technologies areappearing on new cars. A developing technology called Vehicle-to-Vehicle communication, or V2V, is beingtested by automotive manufacturers as a way to help reduce the number of accidents. V2V works by usingwireless signals to send information back and forth between cars about their location, speed and direction, sothat they keep safe distances from each other. Another new technology being tested is Vehicle-to-Infrastructurecommunication, or V2I. V2I would allow vehicles to communicate with road signs or traffic signals andprovide information to the vehicle about safety issues. V2I could also request traffic information from atraffic management system and access the best possible routes. Both V2V and V2I have the potential toreduce around 80 percent of vehicle crashes on the road.More and more new cars can reverse-park, read traffic signs, maintain a safe distance in steady trafficand brake automatically to avoid crashes. Moreover, a number of firms are creating cars that drivethemselves to a chosen destination without a human at the controls. It is predicted that driverless cars will beready for sale within five years. If and when cars go completely driverless, the benefits will be enormous.Google, which already uses prototypes of such cars to ferry its staff along Californian freeways, once put ablind man in a prototype and filmed him being driven off to buy takeaway hamburgers. If this works, hugenumbers of elderly and disabled people can regain their personal mobility. The young will not have to paycrippling motor insurance, because their reckless hands and feet will no longer touch the wheel or theaccelerator. People who commute by car will gain hours each day to work, rest, or read a newspaper.
