Dr. G talked about how to get to the Rally to Restore Sanity and/or Fear, but didn't mention bikes.
Otherwise, it's the same old territory.
What are the rules about cyclists on sidewalks?
The Washington Area Bicyclist Association offers great guides about the rules. They are helpful for cyclists and for motorists:
On the crowded streets in downtown Washington, cyclists are supposed to stay on the streets, not the sidewalks. That doesn't happen, and it's dangerous. Cyclists come at pedestrians from all directions. You'd have to have Linda Blair Exorcist style 360 degree vision to be ready for that.
Police do enforce the traffic laws, which cyclists are subject to. But they're not going to be in enough places to stop all the bad behavior that you're seeing.
Why don't cyclists follow the rules
Saturday night in Adams Morgan I watched as a cyclist blew threw a stop sign into the path of a pedestrian in a crosswalk. Didn't even slow down.
But I can't conclude from that -- or other incidents we all could describe -- that "most" cyclists do any one particular thing. I watch traffic for a living and can't conclude that "most" drivers do any one particular thing either.
What I notice is that many travelers -- motorists and cyclists -- will obey traffic rules when they have no other choice and ignore them when they can.
Speaking of which, ABC7 has a story on the new bicycle traffic light in Alexandria (the first in Virginia). And yes, a lot of cyclist ignore it. But it is odd that pedestrians get a green when cyclists get a red. What's up with that? Why have both?
