Curt Dunnam bought a Chevrolet Blazer with one of the most popular new features in high-end cars: the OnStar personal security system.
The heavily advertised communications and tracking feature is used nationwide by more than two million drivers, who simply push a button to connect, via a built-in cellphone, to a member of the OnStar staff. A Global Positioning System, or G. P. S. , helps the employee give verbal directions to the driver or locate the car after an accident. The company can even send a signal to unlock car doors for locked-out owners, or honk the horn to help people find their cars in an endless plain of parking spaces. The biggest selling point for the system is its use in thwarting car thieves. Once an owner reports to the police that a car has been stolen, the company can track it to help intercept the thieves, a service it performs about 400 times each month.
But for Mr. Dunnam, the more he learned about his car’s security features, the less secure he felt. He has enough technical knowledge to worry that someone else-law enforcement officers, or hackers-could listen in on his phone calls, or gain control over his automotive systems without his knowledge or consent. "While I don’t believe G. M. intentionally designed this system to facilitate such activities, they sure have made it easy," he said.
Mr. Dunnam said he had become even more concerned because of a federal appeals court case involving a criminal investigation, in which federal authorities had demanded that a company attach a wiretap to tracking services like those installed in his car. The suit did not reveal which company was involved. A three-judge panel in San Francisco rejected the request, but not on privacy grounds; the panel said the wiretap would interfere with the operation of the safety services. OnStar has said that its equipment was not involved in that case. An OnStar spokeswoman, Geri Lama, suggested that Mr. Dunnam’s worries were overblown. The signals that the company sends to unlock car doors or track location-based information can be triggered only with a secure exchange of specific identifying data, which ought to deter all but the most determined hackers, she said.
We can conclude from the passage that OnStar is ______.
选项
A、too complicated to use especially for new drivers
B、not as useful and effective as the company claims
C、popularly used among more expensive ears
