1.2 million road deaths worldwide occur each year, plus a further 50 million injuries. To reduce car crash rate, much research now is focused on safety and new fuels-- though some electric vehicle and biofuel research aims at going faster.
Travelling at speed has always been risky. One cutting edge area2of research in motoring safety is the use of digital in-car assistants. They can ensure you don’t miss crucial road signs or fall asleep. The use of artificial intelligence software allows these assistants to monitor your driving and makes sure your phone or radio doesn’t distract you at a vital moment. Most crashes result from human and not mechanical faults.
Some safety developments aim to improve your vision. Radar can spot obstacles in fog, while other technology "sees through" high-sided vehicles blocking your view.
And improvements to seat belts, pedal controls and tyres are making driving smoother and safer. The colour of a car has been found to be linked with safety, as have, less surprisingly, size and shape.
And alternatives to fossil-fuel based petrol, such as plant oils, are a hot area of research. Fuel cells based on hydrogen burn cleanly, and are the subject of a serious research effort,
But whatever is in the fuel tank, you don’t want a thief in the driving seat and there have been many innovations, some using satellite tracking and remote communications, to fight against car theft. These communication systems can also come into play if you crash, automatically calling for help.
Accidents cause many traffic jams, but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road. Such jams can be analysed using statistical tools. Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone’s personal chauffeur, but their latest efforts suggest that won’t be soon.
选项 A、They are developing faster electric vehicles.
B、They are analyzing road deaths occurring worldwide every year.
C、They focus their research on safety and new fuels.
D、They are designing fully automatic cars.
答案C
解析 文章第一段的意思是：在世界范围内，每年发生120万起交通死亡事故，加上5，000万起伤残事故，因此，正在进行的许多研究的重点是安全问题和新燃料问题，尽管一些电动车和生物燃料的研究旨在达到更快的速度。所以，C是正确选项。
