Zoom, I couldn't agree with you more. While I've actually had 2 incidents of anti-cyclist rage aimed at me and/or DH in the last couple of weeks, it's not so common around where I ride, at least in my experience. However, I do find fault with the drivers who go so far over the yellow line to pass that they are driving on the wrong side of the road, as well as the ones who think they are doing you a favor by waving you on at a 4 way stop. However, around here, drivers do that when you are in a car, too. The system of first come, first to go that worked flawlessly in AZ seems to be incomprehensible to drivers here.
I went grocery shopping this morning and I know that now it is the time of year that I never drive up Strawberry Hill Rd on a Saturday morning, because there are large group rides, as every club includes this road on a ride in Concord. So, I go just a little out of my way to get to the store. On my way back, it's usually fine, as riders are rarely coming down the hill, at least in large groups. As I was driving home, there was a huge group of riders coming up the hill. I knew that it was a Bike Ride for Ordinary People ride, as I get their emails, despite the fact I have never gone on one of their rides. I was sure glad I was going the other way. My friend rode with them once last year and most of the people had no handling skills at all. Someone crashed into her DH, who is not that keen on riding to begin with.
So, yes, un-law abiding cyclists piss me off as much as clueless and angry drivers.
