A PROTOTYPE driverless car built by Peugeot Citroen has completed a 325 mile journey from Paris to Bordeaux where it will feature in this week’s Intelligent Transport Systems World Congress. The autonomous car, which uses an array of cameras, radar and sat nav to travel, completed the route without any human intervention. Driving along the motorway the modified Citroen C4 Grand Picasso automatically adjusted its speed and changed lanes to overtake, taking into account other vehicles, speed limits and junctions.
