BikingNurse, I get frustrated with bad cyclists, too. And I really, really, really don't see what the behavior of auto drivers has to do with it.

When a cyclist ran down a 73-year-old women in Central Park, the road was closed to cars. When cyclists grumble at me for stopping to let pedestrians cross the bike path (required by law in a crosswalk), there are no cars present.

When a cyclist bumped me while I was photographing a bird nest last week, there were no cars around. It was just plain, no-excuses rude biking. Nothing to do with cars.
