Passed MOT with the indicator just pushed into the hole like that

No, moron it's clipped in the hole like that.
It's quite secure, you don't know sh*t.
Better my wonky and secure indicator than following some idiot like you with their stupid polished car sitting on the floor, weaving around unsafely to avoid tearing their sump off on bumps in the road.
I've been behind kn0bs like that, and pushed them and watched them bounce dangerously all over the place as they try and get away from the nasty looking Golf diesel loping along at a pretty relaxed pace behind them.
MOT tester couldn't believe how tight the bushings through the car were, that's because virtually the whole front is new.
Camber and alignment to front next, which will sharpen the turn-in some more.
Shouldn't you get back under your bridge to watch the goats walking over it?
