The car is to the honor in this new album by Léonard who sees the Genie explore all the possibilities of the machine, starting with the journey through time. But a real genius has an eco-consciousness and Leonard is no exception to the rule! Besides the wind-up car, he has found a new concept: the auto-stop. Of course, Basile is designated guinea pig of this new experience, since it is necessary to list everything that can happen to a hitchhiker and an unlucky driver. Science is at this price... Our laugh too!
