To the Editor: I do not wish to have an ongoing dialogue with Peter Goldwasser of Transportation Alternatives regarding his answer to my previous letter ("Bad Cycling Behavior," Dec. 4). But I cannot have him accuse me inaccurately without defending myself. He is the one who is incorrect. I have never, nor would I ever, accuse Transportation Alternatives of condoning the unlawful behavior of bikers. I have not done this in my letters, to the media or to the Transportation Alternatives office. Can Mr. Goldwasser just make clear what has been done to alleviate the craziness of the bike riders besides ensuring that they wear helmets? I'm sure we all would like to know. Nothing short of identification on the tail of their bikes, as is the case with cars, can work so that when a biker is not following the rules of the road they should know that pedestrians will be able to identify them. Why is that a problem? Bunny Abraham Central Park West Letters have been edited for clarity, style and brevity.
