Insurance companies have for years offered a compelling tradeoff to their customers:
長久以來保險公司要歷經一番調查后才會為客戶提供頗具競爭力的交易：
they track your driving habits, you save up to 30 percent off your bill for driving safely.
他們會追蹤你的駕駛習慣，為你車險節省高達30％的折扣。
But researchers now say that consumers may be giving up too much privacy in the deal.
但現在研究人員們表示，消費者們也許在諸如此類的交易中透漏了太多個人隱私。
If you install the tracking device in your car, insurers like Allstate and Progressive can gather information about when you drive, your starts and stops and your speed.
如果你在車中安裝有追蹤設備，像好事達和進步這樣的保險公司就能在駕駛中收集你的你的出發結束以及行車速度等個人信息。
To avoid spooking customer fears about Big Brother, most of these devices do not include GPS.
為了避免顧客們聯想到老大哥這樣的設備，大部分此類跟蹤設備都不包含GPS全球定位系統。
But computer scientists say they don't need GPS to get a pretty good idea of where you've been.
但是電腦專家們表示他們根本不需要定位就能判斷你從何而來。
In separate experiments, researchers at the University of Denver and Rutgers University wrote algorithms that use a driver's starting point along with the tracking data to estimate where that driver traveled.
在單獨的相關試驗中，美國丹佛大學和羅格斯大學的研究人員們根據駕駛員的出發點和跟蹤設備信息編寫出程序，然后估算駕駛員的行程。
Are drivers worried their data could be used as evidence in criminal investigations or to catch philandering spouses?
駕駛員們會擔心些信息會為犯罪調查或者抓奸提供證據呢？
Nah. Surveys find that most people think highly of their skills behind the wheel.
并非這樣。研究顯示大部分人都認為自己的駕駛技術非常卓越。
And they'd rather cut their rates than keep their privacy.
他們寧愿享受保費折扣而犧牲隱私。
