Is it time to start calling out bad cyclists?

From a technical aspect, yes, you're right but from an attitude aspect you're ALL wrong.

I agree with Skydancer. Just take the moral high ground, let her do her thang and enjoy the humorous side to her behaviour. After all she's not harming anybody.

In that case why don't we all follow her example? Except at speed obviously because no-one here is a nodder..
