> I wouldn't even be surprised if the stopped driver was waving the turning driver on to "be nice".
When I got my license (12 years ago, UK) my instructor very strongly warned against waving / signalling other drivers through for this very reason. I know others around the same time were warned against it too and I believe it's also part of the Highway Code over here (don't judge me, it was a while ago!).
I still do it, though - it seems rude to be deliberately unhelpful or even obstructive even if it isn't 100% safe / legal for the other driver to go. Not to mention the fact that I'd still expect them to use their own judgement even if a stranger was waving them on.
