Saudi women still can’t leave home without permission from a male guardian. They still are subject to being beaten for their perceived disobedience, with no recourse. They can be divorced at a word. They receive a smaller share of the inheritance. Their testimony is worth half that of a man. They must cover their heads when they do venture out or be subject to arrest. All that is based on Islamic law.
Let's say that in the near-future in Saudi Arabia:
A) A woman wants to get a driver's license.
B) A woman wants to drive to another city in the country.
C) A woman wants to cross international borders by driving from Saudi Arabia to Bahrain.
Does she still need the permission of her guardian? If she does, then this whole "WOMAN CAN NOW DRIVE!" law is utter nonsense.
