The Google Driverless Car is a project by Google that involves developing technology for self-driving vehicles using software called Google Chauffeur.
Google engineer Sebastian Thrun has spearheaded the project, which involves a lidar (light radar) system. A Velodyne 64-beam laser allows the self-driving vehicle to generate a detailed 3D map of its environment. Combining these maps with high-resolution maps of the world, the car produces data models that allow it to drive itself.
By April 2014, the Google team completed more than 700,000 accident-free, self-driving miles.
