I’ve ridden with both types of groups. When I had CB a group I rode with would call out every little patch of sand, every flat rodent, every twig, and what wheel track they were in. Including if it was on the center line. Other groups would toe point all of the same things. Yesterday I was on a charity ride. Top speed of about 40-50 mph. The guy ahead of me would give the single file signal for every bicycle or pedestrian that was “stopped “ on the shoulder of the road.�� several of the groups I ride with have come to the group understanding that a toe point or the gravel sign at a turn is only used when it’s absolutely needed. The trick is to avoid the group herd mentality. When I’m riding with a group my mentality is the same as if I am riding by myself. Always scanning.
