The Limits of Vision
I have ridden motorcycles for around 40 of my 44 years. And as it looks like I can no longer do that, I have moved back to bicycles. And so Micheal Cains post was a welcome read, as were the comments. And in those comments were many regulars (Chris, North, Dragonfrog and Glyph especially) talked about both cyclists and drivers not paying attention to others around them, especially pedestrians. I was reminded of a video that I saw on a motorcycling forum years ago.
People look for what they are told to look for, which is generally things that will hurt them.
