I've seen this used in 'another place' as a cathartic top-blowing exercise.... So...
BRITISH GAS MAN YOU MORON! You KNEW I was there because I got away from the lights a LOT before you. Just because you have got level with me does NOT mean I have disappeared and does NOT mean that you can start edging ever closer to the left because you need to be in that lane. And when I shout 'Whoaaaaaah!' and look in your window I'd be grateful if you would even glance my way, the jump in your seat combined with putting your left indicator on and STILL moving left is NOT useful compared to paying attention and realising the traffic ahead is stopped at red anyway and the left hand lane is partially blocked meaning you gain absolutely nothing from passing me. Which, as we've established from me being alongside you the whole time, you DID NOT DO!
Thank you.
