There’s been an increase in drivers WHO WILL NOT GO INTO THE OUTSIDE LANE!
You see them coming up behind you (usually in a black tank) at a fair lick, then they slow down and sit close behind you, even though the outside lane is completely free. You cannot do anything because there is traffic you are overtaking in the inside lane. If you slow down, they slow down, if you speed up, they speed up. The only way to get ris of them is to find a gap in the inside lane, they then rush off, still in the middle lane.
