Spotted...

Hordes of clueless fuckwits out today as expected - including a chap I unwittingly clouted in the face while indicating left while waiting behing a left turning lorry as he undertook me. Said lorry then took the turn so tightly it clipped the metal railings.

His words of thanks to me: "Oi why'd the fuck did you do that?"

Keep leading by example. There's not a lot else you can do.

I'm not a particularly territorial personality, but regarding the ~1.5m of space on my inside: IT'S FUCKING MINE, SO STAY OUT OF IT!.
