The “driver” sets a destination. The car’s software calculates a route and starts the car on its way. A rotating, roof-mounted LIDAR (Light Detection and Ranging - a technology similar to radar) sensor monitors a 60-meter range around the car and creates a dynamic 3D map of the car’s current environment.
A sensor on the left rear wheel monitors sideways movement to detect the car’s position relative to the 3-D map. Radar systems in the front and rear bumpers calculate distances to obstacles.
Artificial intelligence (AI) software in the car is connected to all the sensors and has input from Google Street View and video cameras inside the car.
