Mercedes-Benz's Future Bus with CityPilot shows how public transport may look in the future. Thanks to CityPilot, the municipal bus is partially self-driving, making it safer and more efficient than conventional buses. It's also more comfortable.The technology -- connectivity, camera and radar systems with data fusion -- is spectacular, but the Future Bus also has an innovative interior design. The bus and its technology are milestones on the path to accident-free, autonomous driving.
