Because safety, and also because people often end debating this kind of stuff: The New York Bicycling Coalition has produced a video about the rules for cars -- and bikes! -- when using the road together.

The video is embedded above. It starts out with the section for cars, focusing on how bikes can use travel lanes and how to safely pass them. Then it flips to rules for bikes, focusing on practices such as signaling and (not) riding on the sidewalk. (Each segment is embedded individually below, if you'd like to watch them that way.)

The video was created in conjunction with the Albany Police Department using a grant from the state. You'll recognize a bunch of locations from around Albany.
