On that subject a few years ago my father too an AARP 55 and alive driving course. One of the questions he got wrong he thought he would stump me on.
What direction do you have your wheels pointed when waiting to make a left turn in the situation where you are in the intersection? He said to the Left because you are turning left. I told him that was wrong. It is straight. The reason is that if you are sitting in the intersection that means there is oncoming traffic or you would be making your turn. If your wheels are turned to the left and you get rear ended your vehicle will get pushed into oncoming traffic. If your wheels are straight you will get pushed into most likely nothing.
