听力原文：Automakers and tech companies are working hard to offer the first true self-driving car, [l]but 75% of drivers say they wouldn't feel safe in such a vehicle. Still, 60% of drivers would like to get some kind of self-driving feature, such as automatic braking or self-parking the next time they buy a new car. The attitudes are published in a new AAA survey of 1,800 drivers. Advocates of self-driving cars argue they would be safer than in cars driven by humans because they wouldn't get distracted or drive when tired. But those surveyed by AAA say they trust their own driving skills. Many feel the technology is too new and unproven. John Nielsen, AAA's managing director of automotive engineering and repair, said tests suggest drivers may be overestimating their own abilities. [2]He also believes they will be more likely to trust self-driving cars as they become more familiar with features such as automatic braking or parking. He estimated that the "comfort level" will increase considerably in five to ten years.
1. What is the finding of the AAA survey?
2. What does John Nielsen say about self-driving cars?

解析：题目问的是AAA的调查有何发现。录音提到。调查中75％的司机觉得无人驾驶汽车不安全，故选C“大部分司机对无人驾驶汽车的安全性感到忧虑”。     

题目问的是对无人驾驶汽车，John Nielsen说了什么。录音提到，John Nielsen认为司机在熟悉无人驾驶汽车的一些功能(如自动刹车、自动泊车)后，会更信任无人驾驶汽车，A“司机在习惯了无人驾驶汽车后会觉得它们安全”与录音表述一致，故选A。
