It is a bit odd in a way, as the slowing down of outside lane to almost a standstill with the other lanes still going - I would often go into lane 1 to continue moving and once the issue has sorted itself out, move across again. Guess it is just luck on whether you get pulled or not (but considering the amount of MLM (possibly including that police car on the PH thread), I find it odd that they selectively chose who to pick up).
