Change is coming from within for those brave enough to fight the oppressive systems. The first I heard of any resistance was in the 90s when a group of Saudi women conspicuously drove around in a car alone in protest of the prohibition.
Personally, I think if every fed-up Muslim woman would take a tip (or more than a tip) from Lorena Bobbit, this problem would end rather quickly.
They were probably stoned to death shortly thereafter.
