问题 Motoring Technology
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.
According to the second paragraph, most road accidents happen due to______.

选项 A、heavy traffic
B、human mistakes
C、engine failure
D、bad weather

答案B

解析第二段最后一句话明确指出“most crashes result from human and not mechanical faults”,选项B中human mistakes即human faults.
