Yeah the the red car was driven by a dozy moron, but what else did anybody do wrong? Spot of sloppy driving, but nowt serious.
First chap pulling away, yeah maybe bit eager, but not obvious if he was really blind to you. Pretty much as I'd expect from anyone trying to pull out in a smallish gap in traffic.
White car pulling over, nowt wrong with that, had brake lights on, even flashed hazards for moment and did actually indicate which way they were going. 90% of all taxis I see in the city will do far worse than this, in far dumber places with much less indication.
Cars you overtook, had to watch this a few times, but I really couldn't see what was so wrong here. Just looked like two average speed cars, you safely overtook. Errrm, am I missing something?
As for the red car, yes, that had SMIDSY written all over it. Next time, you approach a junction with car looking to pull out, consider positioning yourself nearer to centre to be more visible (though staying mindful of oncoming car on other side). Possibly weave a bit - side-to-side motion of your lights is easier to spot and judge distance/speed of. In this instance I don't suppose she even looked, but you could have hit your horn on approach, she may have finally taken notice then, hit anchors and given you spot more room to swerve around. I don't want to say you did anything wrong, but there's no point being right if an idiot puts you in a wheel chair. Have a gander at this near SMIDSY I had:-
