No. You are passing people on the motorway at say 105kph, then come up behind 4-7 car cluster f**k being held up by a lead lemming... so, you put your Ninja mask on and sniper them out with a swerve in front of them from the inside. This is a dangerous move and not fair on the tailgating lemmings just sitting behind him... but its immensely pleasing when they loose their sh*t and freak out.
Wake the f**k up and get real people, its a passing lane, if you are not passing, get the f**k out of it and if you cant handle your car, get off the road.
This move also works well on people who speed up to block you out on either the motorway or passing lanes, guarantied they will jam on their brakes and take a good few seconds to figure out what just happened, like a dazzled possum.
Yes I am an arshole. I apologize if it was your mum driving.
