While they may be years away from mainstream use, self-driving vehicles inched closer on May 5 in Las Vegas, where Daimler unveiled the Freightliner Inspiration truck.

现在在内华达州高速公路上进行测试，这款18轮摩托车是美国许可的第一款自动驾驶卡车，它结合了碰撞缓解技术，例如基于雷达的自适应巡航控制和基于摄像头的车道保存控制，以提供自动驾驶模式驾驶员可以参与。

Not to be confused with a driverless truck, Inspiration cannot pass, merge or perform other complex maneuvers on its own, but Freightliner hopes to reduce driver fatigue, accidents and fuel consumption during long highway trips.
