Tesla sells 'Full Self-Driving,' but what is it really?
特斯拉售卖“完全自动驾驶”，但这究竟是什么？
Over the years, Tesla owners have paid as much as $10,000 for the package, called Full Self-Driving. FSD, which can be purchased as an extra on Tesla cars, is a collection of services that adds to Tesla's Autopilot, the driver-assistance technology that government investigators are taking a look at after a string of crashes.
多年来，特斯拉车主花费高达 1 万美金购买名为“完全自动驾驶”的软件包。特斯拉汽车的完全自动驾驶软件包可额外购买，它是特斯拉 Autopilot 的一套补充服务。在一系列车祸发生后，Autopilot 辅助驾驶技术正受到政府调查人员的关注。
Critics say FSD has not lived up to its name since its debut more than two years ago. The company is making promises that other carmakers shrink from, and its customers think their cars can do more on their own than they really can.
批评人士称，完全自动驾驶自两年多前首次亮相以来一直名不副实。特斯拉在做其他汽车制造商不愿做的承诺。而特斯拉客户以为，他们的汽车能自动完成的工作比车辆实际能做到的要多。
Other automakers like Argo, Cruise and Waymo have been developing and testing autonomous vehicles for years. In each city, they begin by building a detailed, 3D map. Tesla is taking a very different tack. The company and its chief executive, Elon Musk, believe that self-driving cars can navigate city streets without 3D maps. After all, human drivers do not need these maps; they need only eyes.
Argo、Cruise 和 Waymo 等其他汽车制造商多年来一直在研发和测试自动驾驶汽车。他们在每一个城市先构建一张详细的三维地图。而特斯拉正在采取截然不同的策略。该公司及其首席执行官埃隆·马斯克认为，自动驾驶汽车无需三维地图便可以在城市街道上行驶。毕竟，人类驾驶员不需要这些地图，他们只需要眼睛。
For years, Tesla has argued that autonomous vehicles can understand their surroundings merely by capturing what a human driver would see as they speed down the road. That means the cars need only one kind of sensor: cameras.
多年来，特斯拉一直声称，自动驾驶汽车仅需捕捉人类驾驶员在路上快速行驶时看到的景象，就能理解周围环境。这意味着汽车只需要一种传感器：摄像头。
Given the speed of cameras and the limitations in the algorithms that analyze camera images, there are still situations where such a setup cannot react quickly enough to avoid crashes, said Schuyler Cullen, a computer vision specialist who oversaw autonomous driving efforts at the South Korean tech giant Samsung.
曾经负责监督韩国科技巨头三星自动驾驶相关工作的计算机视觉专家斯凯勒·卡伦表示，考虑到摄像头的速度和算法在分析摄像头图像方面的局限性，这种装置仍存在反应不够迅速、难以避免车祸发生的情况。
