A new European project is being launched to develop and test technology for vehicles that can drive themselves in long road trains on motorways.

Key partners include Ricardo, which has outlined exactly how the system could work in the real world. In normal motorway driving, a row of cars would inch up to each other, travelling at normal speed in a close-formation convoy. More
