We all need to take responsibility for our own experience. I research any group I'm thinking about riding with, if their style doesn't match with mine it's my responsibility for what happens on the ride if I join them. I've been dropped from groups, so what, my problem I couldn't keep up, but I never get upset about it. I've also been in groups that ride the usual pace and people get dropped off, sorry, must not be the group for you today. I've been a member of clubs where people join rides that they clearly are not up to the normal pace of the group, it takes a very short distance for them to be dropped. They often complain to club leaders, who usually offer to let them lead slower groups with a no drop policy. Few, if any ever take the offer and lead slower groups. It's everyone's responsibility to find the right ride group, or start your own.
