Some depends on the ride leader especially when newer riders are involved.
I'm done with group rides after two with the same leader ...on the second one I told them clearly I won't lead but I'll show you the roads in PA.
Arrogant ass riding a non-stock bike that couldn't get by a gas station.
First crash the rider wouldn't listen to advice online that he was not ready to move from a 250 something to a 600cc within 3 months.
Tried to keep up with two guys who knew the roads....he was very lucky as he low sided at speed and ended with his nose 12" from the butt end of a guard rail.
Too new to know not to try and keep up ....
Same lead ...takes off with his "good friend" who is riding a very new FJR. Now an FJR on PA twisties is not ideal. Leader says "I looked in my rear view mirror and saw him pinwheeling into the bushes.'
Two rides, two crashes....quite enough of that nonsense and what really put me off,.,,wanted to know where he could buy beer.
I like to ride in pairs with comms on. It's enjoyable and adds to the ride....swap stories, figure out what to eat, how is fuel ....we found a neat solution....front rider watches for road hazards...tail rider navigates and advises the lead where to turn and when.
Splits the work and we had a hoot scaring drivers on the very twisty Port Albernie road with far too many blind corners. Kid on the fast bike would get by a car or two...Dad on the mule could pass safely on the blind corners thanks to kids heads up.
I do find chatting a positive contribution instead of hand signals. But groups?? naaaaaah.
