I have my own little group of 4 that are well disciplined riders and we know how to keep ourselves and others safe. It is another group of 20-25 most times that are all over the place. Not my group, not the ride leader so I just ride along and keep myself protected from the others. As in, spot the bad handlers and stay away.
I have mentioned such issues to said ride leader but he's one of them.
It's much safer to avoid the group once realizing that there are too many risks riding with chaos.
