The worst thing that you could possibly imagine happened. My husband is a dedicated urban bicycle commuter. I was a bicycle commuter until I got a job that required an automobile. And as I was making a left turn I collided with a cyclist who was injured. The sun was behind him and there was intense glare and though I could see cars, I literally did not see the cyclist.
I feel so awful. I wonder if using a light during the daytime would make a difference in situations like this.
