问题     It used to be the case that if you left your car in the sun on a hot summer’s day, then getting back in again afterwards was agony. Not any more. Now you press your key into the door lock and the car’s air-conditioning system automatically starts cooling the interior. You just have to wait a minute before you get in.
    That is just one of the newer gimmicks that make the modem car so much more comfortable to drive than those produced not so long ago. Another innovation is the self-adjusting seat. When you put the key in the car door, the front seat will automatically adjust itself to the driver’s preferred driving position.
    These ideas were dreamt up at General Motors’ research laboratories in Detroit. The laboratory was set up in the mid-sixties, in response to consumer groups who attacked the company for its safety record. Since then, the company has set itself an impossible goal: that you’ll be able to walk away from most car accidents.  It spends roughly one billion US dollars every year on safety research.
    The company is working on helping drivers survive crashes at higher speeds. The idea is that the driver won’t fly out of the car because of his seat belt, He won’t be crushed by the side door coming in because it will be strengthened by a side beam. His ribs won’t be crushed, nor his organs injured by the steering wheel, because it will bend when the body hits it. His face won’t be slashed by broken glass because the windscreen won’t shatter.
    Every year, the total world-wide bill for injuries of all types is estimated at US $ 500 billion. Transport injuries of all sorts account for one quarter of this. This gives some indication of the size of the problem the scientists working at General Motors’ research laboratory have set themselves.
The major concerns of General Motors’ research laboratory are ______.
选项 A、traffic regulations
B、driving techniques
C、the car’s interior structures
D、innovations in cars
答案D
解析
