Is it time to start calling out bad cyclists?

+1, oi is the only thing I can do loudly, it may seem rude/make peds jump but then if they'd followed the green cross code when I have priority I wouldn't have to shout...

But that said there's nothing wrong with #2 on your list. I'd be politer if I could, but when someone's obliviously stepping out into your path and you're going at speed, then there's only time for an instinctive monosyllabic yelp to prevent a crash.
