Well bikers are angry because they don't want to be treated as cars OR as pedestrians, but those are the only two classifications much of the US has. Many people on a bike are unable to even maintain 25mph for a slow city road, let alone 45mph or 55mph, so treating them like cars is ridiculous. But they do commonly go over 3mph, which is the speed of your average pedestrian.
Bikers want to be treated like bikers. Unfortunately that classification doesn't really exist in the US so it becomes situational.
