Looks to me like another instance of a group of arrogant cyclists blocking an entire lane of a 2-lane road and refusing
to move to single file so a car can pass them. I’ve experienced this BS in Florida, having to go 15mph in a 35mph zone because these jerks want to ride next to each other in a group and far outside the bike lane. They do it to be a-holes and they know it.
Pass in the other lane.
