If the issue is not leaving the house, then why driving? Why not say they can’t use a car service, or a bus? Or just say women shouldn’t leave the house?
Be realistic. The aim is not to disable women from leaving the house. The aim is to take away the luxury of driving. Ask anybody who drives who suddenly lost his car for two weeks. Obviously, you can still get lifts, take taxis or use the bus. But that is all inconvenient. You aren’t your own boss. It definitely limits leaving the house to necessities rather than luxuries.
The question is simply whether the advantages are outweighed by the dangers of such travel (see OP).
