Looked like abject stupidity or discourteous riding for the most part. There were several that should not be held up as examples of cyclist stupidity. The clip at the 5 minute mark and the 5:10 mark showed cyclists who had established themselves in the lane and had the right of way. At the 1:10 mark the cyclist provided an example of why cyclist don't like to hug the right. It invites a squeeze pass and leaves no room for error. Further, that cyclist was riding in the door zone. That's something I NEVER do.
