    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 dangerous. One advanced area of research in motoring safety is the use of digital in-car assistants. They can ensure you don’t miss important road signs or fall asleep. 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" big vehicles blocking your view.
    And improvements to seat belts, pedal(脚踏) controls and tyres are making driving smoother and safer. The colour of a car has been found to be linked with safety, as have, les.s surprisingly, size and shape.
    But whatever is in the fuel tank, you don’t want a thief in the driving seat and there have been many innovations (创新). Satellite tracking and remote communications 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 analyzed using statistical tools. Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone’s personal chauffeur (司机) ,but their latest efforts suggest that won’t be soon.
Which of the following safety developments is NOT mentioned in the passage?
选项 A、Windscreens that can help drivers to improve their vision.
B、Radars that can help drivers to see obstacles in fog.
C、Devices that can help drivers to see through big vehicles.
D、Improvements in seat belts, pedal controls and tyres.
答案A
解析 选项B和C的内容在文中第三段提到“Radar can spot obstacles in fog,while other technology‘sees through’big vehicles blocking your view”,选项D在第四段中第一句话提到“…improvements to seat belts,pedal controls and tyres are making driving smoother and safer.”只有选项A未被提及。
