I have absolutely no beef with perfectly fine parking! It's a part of LIFE we can't avoid it.
But some people - too many people - are just really bad at it and there's no denying or avoiding it.
Another one I've just remembered - the junction out of my estate onto the main road, some Karen likes to park her jeep on the grass verge even though she has a fuck off driveway. It doesn't so much restrict the view of oncoming traffic, it obliterates it. Anyone with a HINT of self awareness would notice that.
I know what you mean about facebook groups though - she was called out on our local group (not by me) and it all got a bit awkward. She put some really bad LEGAL response claiming to be a lawyer (clearly not a lawyer) and threatening defamation

I couldn't help myself but LOL in response. She wasn't amused.
