问题    On a clear morning in early May, Brian Lathrop, a senior engineer for Volkswagen’s Electronics Research Laboratory, was in the driver’s seat of a Tesla Model S as it travelled along a stretch of road near Blacksburg, Virginia, when the car began to drift from its lane. Brian had his hands on the wheel but was not in control of the vehicle. The Tesla was in Autopilot mode, a highly evolved version of cruise control that, via an array of sensors, allows the car to change lanes, steer through corners, and match the sudden movement of traffic unaided. 【F1】As the vehicle—one of a fleet belonging to Virginia Tech’s Transportation Institute, which Brian was visiting that day—lost track of the road markings, he shook the wheel to disengage Autopilot. "If I hadn’t been aware of what was happening, it could have been a completely different outcome," Brian told me recently.
   While one’s first time behind the wheel of an autonomous car (or in front of it) may feel perilous, Volkswagen’s research has shown that trust between human and vehicle blossoms rapidly and, in many cases, completely. 【F2】A decade ago, according to Brian, the company ran a series of internal studies in which it put people in the driver’s seat of a car that they were informed was fully autonomous. 【F3】Behind them, behind a curtain, sat a driver, who controlled the car using a camera feed of the road ahead, as if playing a video game. "We found that people get comfortable very quickly—almost too quickly, in fact—in letting the car drive itself," Brian said. 【F4】Free from the activity of driving, most people experience what researchers refer to as passive fatigue—a state in which awareness is dulled. It can set in after as little as ten minutes.
   Tesla strenuously warns consumers to pay attention while their car is in autonomous mode, but the warning may not be strong enough. On Thursday, Laura MacCleery, the vice-president of consumer policy and mobilization for Consumer Reports, said that the very name of Tesla’s self-driving feature-Autopilot—"gives consumers a false sense of security."
   【F5】This is the paradox facing auto engineers: how to design self-driving cars that feel trustworthy while simultaneously reminding their users that, no matter how wonderful a given model’s safety record, no driver—human or artificial—is perfect. How, in other words, to free drivers from the responsibility of driving, while burdening them with the worry that, at any moment, they will need to take back control.
【F3】
选项
答案而在实验者身后，在一道帘子后面，坐着真正的司机，司机依靠摄像头反馈的前方道路信息驾驶汽车，仿佛在玩电子游戏。
解析 ①本句是主从复合句。句子的主干是倒装句，谓语sat在主语a driver前，这样表达所示的画面感更强。②句首的两个behind介词短语是两个并列的地点状语，说明主语“司机”的位置。③定语从句修饰的是a driver，说明这是真正操控汽车的人。④句末as if引导的是方式状语，说明这种驾车方式就像玩电子游戏一样。
