Sorry Joe, that is not what happened. From Jpost:
In a letter sent out last week, the leading rabbis of the Belz community declared that female drivers fly in the face of “the traditional rules of modesty” expected in the hassidic camp. The letter also stated that beginning in August, children who are driven to school by their mothers may be banned from academic institutions.
The letter claimed that as more mothers begin to drive their children to school, there has been an increase in “resentment among parents of pupils of our institutions.”
If you read the letter, it says that this is a “new” Takanah.
