One of my co-workers was doored today. I have never been doored, but I have read about it and heard some horror stories from friends and acquaintances, nor have I been with someone who was recently doored. The fear was etched on her face as she described the circumstances of the event; hearing and sensing the truck coming up on the left to pass her, and watching the person open the door of the parked car even as they were looking in the side view mirror directly at her as she approached. She had a choice; veer into the path of the approaching vehicle or level her shoulder at the car and attempt to take a glancing blow. She chose the latter, and did not go down, but in some way swiped the car and remained upright. As she described this, her eyes were wide and her voice shaky. She said she felt like she was going to be sick. I felt terrible for her. It reminded me of how tenuous my own riding can be. The times I've let me attention wander as I enjoy my ride to or from work, enjoying the cool air of the morning or the evening. The few times I have let my guard down I have had some close calls, and they scared the hell out of me.
If we are to continue riding in our semi urban environment, we must be attentive, and work to make others aware of cyclists right to the road.
