French people spend an average of 50 minutes commuting every day. Via train, bus, metro or alone in a car: the range of possibilities has remained limited for years.

Carpooling, on-demand or self-service systems, autonomous vehicles, data proliferation and inter-modality are the new components of the model under construction. Will it be possible to balance the interests of all users with those of new private actors? What role is there for public authorities, who were once the conductors of these daily ballets? What will be the new financial equations? How can we ensure that this reshuffle works in favour of the energy transition?
