With family, especially immediate family, you talk about and work it out. If it's friends you don't see eye to eye with you save the friendship by not riding together.

For my part, I have enough responsibilities and worries, and enough friends and family I care for and about, that I don't see any need to fritter away energy over concerns about strangers, especially since there's so little I can do about it anyway.

Years ago, I used to join a local weekly pickup ride, that often had 30 or more riders. This was a very fast paced bunch ride, and over a number of years grew to become very sloppy with an accident/injury rate as befits riding that way. Solution--- I stopped riding with those people. The ride is still going strong, and there are still regular crashes, but it's no longer my problem
