When the car was created, it greatly facilitated people's travel, we put forward higher requirements for it, hoping that it can be like the "magic carpet" in the fairy tale world, just one command can carry us to our destination. With the rapid development of science and technology, Automotive Engineers integrate artificial intelligence, visual computing, lidar, camera device and precise positioning system into automobiles, so that they can no longer rely on human's active control to achieve automatic and safe driving, and automobiles become the "magic carpet" on the road. From 2014, Google first demonstrated its autopilot prototype vehicle. So far, there has never been a L4 class self driving car that has been sold in the market. This great idea has never been able to escape from the laboratory door and stay in the test vehicle stage. In 2017, Robin Li received the first automatic driving ticket in Beijing's Fifth Ring Road. By 2018, a woman in Arizona, USA, was automatically driven by Uber.
