Yeah, I read the methodology, but I don't believe it. Look at the angle of the car in the WOL picture. It appears to be moving from the inside lane to the outside lane, probably to overtake the motorist in front.
Another thing is that the BL picture has traffic stacked up in the inside lane, limiting the amount of lateral movement for the motorist in the outside lane.
