Autonomous vehicles are being designed by AI, then built by a combination of robots and humans trained by augmented reality.  They often incorporate advanced materials and are now beginning to use 3D printing for structural components. They incorporate advanced energy technologies for batteries, charging, energy management, and charging station location and routing. They use satellite based positioning systems to determine location, and exploit real-time AI, sensors, and actuators to perceive their surroundings, predict what other cars and pedestrians will do, plan actions such as steering and braking, and then execute them.
