"Tough luck if you come from far away for work,"

If you come from far away for work, in Paris, you're using the RER trains.

"if you are old "

If you are old, maybe you should not be driving. Some of us would prefer not to have to dodge geezers driving land yachts.

"or handicapped"

The ban does not apply to mobility scooters.

"if you planned a day in the countryside with your family of four children, etc."

Take the RER. Pas de problem, monsieur.
