First of all, I am very familiar with the conditions where this collision occurred and I was out and about at the time it took place. 

As to whether I would be a poor excuse for a driver if I were to run into a pedestrian: Of course I would. If I were to run into someone, I would cease all driving immediately. I'm getting old, so I have made sure that I have some young people who will tell me when I need to stop doing what little driving I do. They will alert me when it's time to stop driving, so hopefully I will never strike a person with any motor vehicle I operate.

I have a friend who was distracted and ran a red light over thirty years ago. She decided then and there that she didn't have the focus to drive and stopped driving. She's not stupid or lacking in abilities as her ivy league PhD in chemistry attests to, she simply sees driving as too great a risk for her. I wish we had more people with her ethics.
