I saw 1/2 of the youtube video and couldn't watch anymore because it made me too angry.
This looks like a ride for every narcissistic cyclist in the area. How can cyclists campaign to ask drivers to "share the road" when there are videos like this that show cyclists acting like they own the road. Near the beginning, it looks like there's even a bike lane or a fairly wide shoulder and yet these folks insist on taking up an entire car lane riding anywhere from 3-5 abreast. At several points it's clear that they are taking up more than one lane. Overall, it's a pretty pathetic display of selfish behavior that constitutes nothing more than an organized middle finger to the drivers. Problem is this kind of behavior hurts the rest of us who try to return the courtesy that overwhelming majority of drivers show us.
I only watched half of it too because I had to get up and dance.
