I was riding to work this week, and as usual waited until the cars had stopped before filtering forward. I couldn't get all the way through so stopped a few cars from the front. Next thing you know, the car on my right is inching forward very close to me. I feel the front wheel rub against the outside of my boot, then watch as the car mirror pushes against my handlebar end, scratches, and folds in. No damage to my bike; metal on plastic is no contest. QUE? This cager was clearly annoyed that I had stopped in front of them and was so determined to push forward that they sacrificed their mirror! I have long ago banned myself from aggression on the roads, so all I did was turn and stare into the front window. The guy in the passenger seat was mouthing "sorry" to me while the young woman in the driver seat stared fixedly ahead. Perhaps some domestic strife coming? Anyway my day improved as two other drivers further down the highway pulled to the side to let me through whilst filtering. Of course by then the first crazy cager was long behind me. Anyone else had cager experiences that just don't make sense????
