Noticing that sometimes when I'm driving I have internal talking

(Chapter 7 Driving While Living with a Memory Impairment in my book)

I recently noticed something while I was driving. It is not happening every time I drive, but only sometimes. There are times when I have "internal talking" while I am driving. In other words, it is talking that is just in my head. Today the words that I'm saying in my head are "red light, I need to stop." I'm not really sure how long I have been doing this. I'm sure that this is helpful to me. Most of the time, I am alone in my car and even if someone was with me, they would not be aware that this is happening.
