Indeed, especially in cities that are still riddled with cars but you can manage without if your job is not in a remonte location or doesn't require a car. In the countryside cars are still mandatory. Trains once were reachable from many small villages but many stations have sadly been removed.

I hope the train network will improve, or at least not degrade.

I like being able to go to work by train every day, and I also like being able to finish my day job in the south east of France and be able to reach north west by 11 PM, doing my stuff or sleeping during the trip, and planning to do this only a few days before.
