Dear Streetsbloggers: How Do You Spread the Word About Bike Lane Rules?

To assist in the ongoing effort to better articulate a set of social norms for the endless variety of circumstances one encounters on city streets, we're passing on this request from a reader. "Midtown Biker" asks for advice on the best way to handle these situations:

1. Another biker is riding the wrong way on a one-way street (West 90th Street) andhogging the bike lane. I tried "Please ride with the traffic" and got cursed at.
2. I'm riding in a bike lane. A car cuts me off, then stops short,double-parking in the bike lane. The street is now impassable. I tried, "Pleasedon't block the bicycle lane." The doorman from the driver's apartment buildingsaid to the driver, "You do whatever you want. You want to park here, don'tlisten to him." Any suggestions?
