I did a great wave the other day at some knob jockey who just had to get past me as soon as he had finished munching on our bumper and the single lane expanded to two lanes.
His lane was already filled with fellow speedy boarders, who'd have thought, leaving us steaming past on the inside ignoring him trying to squeeze back in, borrowed the arm out the window downturned Vee signal from Sons of Anarchy, I hope it doesn't mean nice driving buddy.
Edit, apparently it's pretty much peace out so that's annoying.
