Close to a year without any aggressive caged-wheelchair incidents? I haven't had a year like that in over three decades. Hell, I haven't had a week like that in more years than I care to remember. I am really living in the wrong place.

Regarding your incident: it always amazes me how uncomfortable the carcissists are with having their anonymity stripped away while on the road. My personal favorite way to do it is when I can follow them to the store they are going to (I usually get there first since I don't have to hunt down a parking space and waddle to the door from the parking lot). I then approach them (smiling) and suggest that, "It's time". They usually ask what I'm talking about and I explain that it is time for them to give up their driver's license and express my condolences that they don't have a close family member who will tell them that they are just too dangerous behind the wheel to continue driving. About this time most of them recognize me as the cyclist they just buzzed or cut off and they usually apologize. Sometimes they don't remember seeing any bikes on their way in; this sometimes rattles them and sometimes makes them angry. Either way, I do my best to be gentle and appear concerned for them. I have no way of knowing if this improves their driving, but it does make me feel better and I think it puts a human face on their notion of what a cyclist is.
