     Like many other small boys, I was fascinated by cars, especially because my oldest brother was a bit

of a car guy and subscribed to cool magazines like Car and Driver and Motor Trend. Every so often, one of those magazines would run an article on the "Car of the Future". They featured unconventional things

like small nuclear reactors as power sources. Yet, frankly, my car doesn't do anything that my brother's

Studebaker didn't do. It goes, it stops, it burns gasoline. I still have to steer it, and it still runs into things if

I don't steer it carefully.

     But guess what? All of these things are likely to change in the not-so-distant future. It may not burn

gasoline, I may not have to steer it, and it may be a lot better at not running into things.

Airbags (安全气囊) aren't the be-all and end-all in safety. In fact, considering the recent news about

people occasionally being killed by their airbags in low-speed collisions, they obviously still need some

development. But they aren't going away, and in fact, you can expect to see cars appearing with

additional, side-impact airbags, something some European car manufacturers already offer.

     Better than systems to minimize injury in the event of an accident ,however, are systems that minimize

the likelihood of an accident happening. Future cars may be able to remove many of the major causes of

accidents, including drunk-driving, and tailgating (与前车距离过近). Cars could be equipped with

sensors that can detect alcohol in a driver's system and prevent the car from being started, for example.

As early as next year, you'll be able to buy cars with radar-equipped control systems. If the radar

determines you're closing too quickly with the car in front, it will ease up on the throttle (油门). 

     Will cars eventually be able to drive themselves? There's no reason to think it won't be technically

possible, and Mercedes is working on a system that can brake, accelerate and steer a vehicle down a

highway on its own. Nobody really expects people to give up all control to their cars, but such systems

could be used as failsafe (自动防止故障)systems to keep cars on the road and bring them safely to a

stop even if the driver suddenly became disabled.
