Overall, autonomous car will impact our society positively through mature technology and proper legal regulations in the future, but it is not a good idea to promote autonomous cars now.
A car is operated by automation with the help of an artificial Intelligence computer. Autonomous cars, also called as self-driving cars, driverless cars, or robot cars, are autonomous vehicles that are capable of traveling without human operator such as handing on the steering wheel or stepping on the brake. Besides the ordinary equipment of car, autonomous cars also need the help with a number of sensors and other digital devices, for example, radar used for adaptive cruise control, ultrasound used for assisted parking, cameras used for lane-keeping and back-up assistance, navigation aids used for determined car's position, and lidar used for created a detailed map of the car's surroundings as it moves (How an Autonomous Car Gets Around). These cars have advanced control systems to collect sensory information of their surrounding environment, process this information and identify appropriate paths to get to the destinations. They not only can spot objects on the road ahead and control the brakes to prevent accidents, also can keep a safe distance from the front cars and maintain a safe speed. When it is necessary, they will speed up, slow down, and change lanes automatically by detecting other vehicles, pedestrians, and traffic lights. In addition, the "Vehicle to Vehicle Communication" system allows autonomous cars on the road to be able to communicate with others avoiding any collisions (Newcomb). Significantly, autonomous cars are designed to respect all traffic laws and avoid any possible obstacles, but operators of autonomous cars must be able to take control of their cars at any time by law (Guizzo). According to the IEEE, 75% of all vehicles on the road will be autonomous cars by 2040.
