Weekly Challenge French Grand Prix / Overtaking via blue flags

[Pitchpole 10]

So this weeks challenge, finish 6th or higher as Riccardio. So it's pretty easy to just stay right behind Hamilton and pass all the cars that get blue flagged and pull over to let Hamilton get through. I kind of feel like one of those people that follow the Fire Engine with it's sirens on through red lights and around all the cars that pulled over, very illegal. Anyway, this is the second time codemasters has set up a scenario like this where you can shadow the leader to pass other cars that get blue flagged, has this scenario ever happened at a race in real life?
