An appartement in Paris for a family is at least a millions dollar, you are telling me they can't afford a car? No, moving in car is simply inconvenient here. You can walk or take the public transit to get where you want, it's just faster. Lots of parisians have a car, often in a parking spot far from their home, and rarely uses it. Someone commuting to Paris with a car instead of public transit is seen as someone mad loosing their time in bad transit. Again, watch the videos of the person I sent, you prone bringing a new point of view while it's the same carbrain arguments that is unable to even imagine an alternative, that already exists.
