Fewer young city folk are buying a car, but they want to stay on the move all-the-same.Car-sharing firms generally require you to commit to membership and only have regular passenger cars. MU is a comprehensive new concept from Peugeot in which customers only pay for what they actually use. They can choose from both cars and vans and also hire bicycles, motorscooters and accessories like roof boxes and sat-nav systems. Berlin is the first German city to join the MU network, with more cities due to follow.
