More recently, however, General Motors made a self-driving car in 1958 that adjusted its steering wheel based on the alternating currents given off by a wire placed inside the road. While the vehicle did actually drive itself, it does not qualify as the first autonomous vehicle because it depended on wires placed inside the ground. The world's first autonomous vehicle was made by S. Tsugawa and several of his colleagues at Japan's Tsukuba Mechanical Engineering Laboratory. However, German engineer Ernst Dickinson is regarded as the pioneer of the autonomous car. In 1987, he developed the VaMoRs which was capable of traveling more than 90 kilometers per hour (55 mph) for about 20 kilometers (12 mi). Seven years later, he made the VaMP, which could recognize road signs, know its own position in a lane, detect other vehicles, and even decide when to change lanes. And a year after that, he and his team made another autonomous vehicle which traveled from Germany to Denmark. The vehicle had a maximum speed of 180 kilometers per hour (111 mph) and was controlled by a human for about 5 percent of the journey.
