Automobile manufacturers still promise speed and freedom, although the average speed of cars in major European cities is lower than that of 19th century carriages. On average, each vehicle is parked for 99% of its lifetime, not fulfilling any function but wasting valuable space. Thomas Feichtner designed a mobility concept as an impulse for discussion. A self-experiment, from concept to sketch to rendering. A vehicle usable like a room on wheels. As a rolling workshop, a medical service, a repair store or a sales booth. The car, not as a status symbol but as a functional object.
