None, except that cycle training often help you figure out the best course of action if such behaviour occurred.
For instance, if someone's calling you out, the best course of action is to simply acknowledge them and carry on riding, this way you're not adding more fuel to the fire.
If it escalated, just simply drop back and let them go/take a different path temporary, and I'm sure you don't need to be explained why as other such as cliveo, skydancer, Object et al;ll has done so in such detail with deep concern for your wellbeing.
I'm very glad you're ok though, that something I really don't want to experienced in my life.
Hey ed, where did you do your cycle training? I'm thinking of signing up.
