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 smoot- her and safer. The colour of a car has been found to be linked with safety,as have,less surpris- ingly,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 statements is true of robotic drivers?
A: It will take some time before robotic drivers are available.
B: Robotic drivers are not allowed to drive on busy roads.
C: Robotic drivers can never replace human drivers.
D: Robotic drivers are too expensive to use.

Every day 25 million U.S. children fideschool buses. The safety record for these buses is much better than forpassenger cars; but nevertheless, about 10 children are killed each year ridingon large school buses, and nearly four times that number arc killed outsidebuses in the loading zones. By and large, however, the nation′s school childrenare transported to and from school safety.
Even though the number of school buscasualties (伤亡事故) is not large, the safety of children is always of intense publicconcern. While everyone wants to see children transported safely, people aredivided about what needs to be done particularly whether seat belts should bemandatory (强制).
Proponents of seat belts on schoolbuses--many of them parents and medical organizations argue that seat belts arcnecessary not only to reduce fatality and injury, but also to teach children lessonsabout the importance of using them routinely in any moving vehicle. A sidebenefit, they point out, is those seats belts help keep children in theirseats, away from the bus driver.
Opponents of seat belt installation suggestthat children are already well protected by the school buses that adhere to theNation Highway Traffic Safety Administrations (NHTSA) safety requirements setin 1977. They also believe that many children won′t wear seat belts anyway andthat may damage the belts or use them as weapons to hurt other children.
A new Research Council report on school bussafety suggests that there are alternate safety devices and procedures that maybe more effective and less expensive. For example, the study committeesuggested that raising seat backs four inches may have the same safetyeffectiveness as seat belts.
The report sponsored by the Department ofTransportation at the request of Congress, reviews seat belts extensively whiletaking a broader look at safety in and around school buses.

According to the passage, the"school bus" is ______.查看材料

A.the bus offered by the school
B.the bus that has no difference from thepublic bus
C.the bus that is driven by the students
D.the bus that is not safe
