Is it time to start calling out bad cyclists?

It really is, you might not like that, you seem like the caring type but some people don't want your opinion or concern. That's life. You're free to pull people up when you think you see them doing something wrong, that's your choice, your right, but I am not convinced it's the solution. I think this forum is big enough and more than capable of coming up with a better approach.

bcr, I'm all for having an adult discussion about this issue of calling out versus keeping quite but it has become tedious been to watch you troll this thread, contradict yourself, make sweeping generalisations, personal jibes, and repeatedly state that 'there must be a better way' without actually suggesting one. I don't want to throw fuel on the bigbonfire but I do just want to respond to your comments to me above.

I'm quite sure that not everyone wants to hear my opinion, just as they don't want to hear yours, neither here nor on the road. The fact is, I rarely do advise anyone.

My point though, is that you seem to be under the illusion (or delusion) that one person's actions on the road have no impact on another - each to their own.

Or at least, as long as they don't affect you directly, it doesn't matter and it's not your business to say anything - "their life to live" as you say.

If all of us, as members of a community, decided it was acceptable to give someone "their right to live", so sit back and watch them endanger themselves and others (and that includes the devastating psychological consequences experienced by any driver who through no fault of their own hits a cyclist) then that's not a community I would want to be part of.
I sure as hell wouldn't want to cycle if everyone thought this way!

Tenners' point about striving to "raise awareness within the cycling community of issues and dangers which do arise, and trying to prevent them from causing anyone harm" is spot on. Going a step further and raising awareness within other road user groups, particularly HGV's is even better. This isn't about being self-righteous or preachy.
