As for telling people about the dangers of undertaking lorries etc - I do this as I don't want to see fellow cyclists killed. One thing I have observed is that the women who I've spoken to when this type of thing has happened, they've all (without exception) taken on board my advice (or at least appeared to) and had a reasonable conversation about it unlike the men who either know better 'I do it all the time' or take massive offence as if I've accused them of being a paedophile or something.
Now I'm not aware that my approach is any different when raising this issue with men or women but their reactions are quite eye opening.
