This is probably the scariest thing for a cyclecommuter. I once talked to a guy in Lenonia on my way to work. Jack and I were at a stop light at a major intersection. We were chatting about something and this guy on the sidewalk next to us chimes in. He told us about a bad accident he had getting hit from behind. The lady was an "exotic dancer" and was not paying attention to the road ahead (I forget why). She hit this guy and he suffered serious back injuries and has to wear a back brace for the rest of his life. It was a strange and sad story but makes you realize just how good we have it to be able to enjoy riding...
