Crazy Drivers: Ms. Can’t-Decide-Which-Way-To-Turn

You are behind Ms. Can’t-Decide-Which-Way-To-Turn as she enters an intersection. She starts to turn right, then left. Then right. Then left. Her car is weaving violently. Then she commits to turn left, well into the intersection. Out of God’s blue sky, she suddenly decides she should have turned right and does a wide turn back, as if pulling a pack of water skiers, narrowly missing a car already turning right.
