Is it time to start calling out bad cyclists?

i hardly ever see anyone doing this yet it does more than just enables you to look over your shoulder, it tells other road users that you are about to do something because you are looking at what is moving into the space where you want to move to.

I've seen a lot of people talk about "eye contact" but i find that quite hard - i very rarely, if ever, can be sure i've made eye contact, i find it hard to locate the face behind the windscreen, and for some reason i usually look at the "face" of the car - y'know the radiator and lights, i think it's some childish thing on my part - well, at least it means i see the indicators...

But i do look over my shoulder a lot, partly as a way of communicating to drivers that i want to do something other than keep going in the position i'm in. Mind you, i look over my shoulder quite a lot anyway, i'm a bit twitchy like that, you can hear the cars slow down a bit just in case i'm about to do something... that probably isn't so helpful on my part.

Hey, anyone here use mirrors? Maybe i'd be less twitchy if i had one. Or maybe it'd just be a thing to distract me from the stuff around me and therefore not a good idea...
