Frankly, cmtbiz, I'm nopt sure from your post that I can determine the point of the post. Are you supporting the radio announcer or not? Are you, too, fed up with cyclists? Are you a road biker yourself, and what do you really think of all this.
True, there are cyclists, especiall in the urban scene (I see this every time I ride in Seattle) who do not help our image. We need to follow the rules and show respect for motorists. However, there are lots of drivers who could learn to do the same. They cut us off, too, and don't leave adequate space for bikes.
As a cyclist, I know I have to be extra cautious and defensive and take care of myself. I don't stand a chance if I don't do everything I can to protect myself. For me, that means being hyper alert and always keeping an eye in my mirror. Also, we can't anticipate what a car is about to do. Half the time (not an exaggeration) they don't signal for turns, and sometimes when they do, they don't turn or they turn the other direction.
So follow the rules of the road, wait your turn at intersections, and be safe!
