Elderly ladies in a car

Two elderly women were out driving in a large car - both could barely see over the dashboard. As they were cruising along, they came to an intersection. The stoplight was red, but they just went on through. The woman in the passenger seat thought to herself "I must be losing it. I could have sworn we just went through a red light." After a few more minutes, they came to another intersection and the light was red again. Again, they went right through. The woman in the passenger seat was almost sure that the light had been red but was really concerned that she was losing it. She was getting nervous. At the next intersection, sure enough, the light was red and they went on through. So, she turned to the other woman and said, "Mildred, did you know that we just ran through three red lights in a row? You could have killed us both!" Mildred turned to her and said, "Oh, crap, am I driving ?"
