If you "lot" think you are puzzled, well so are we. And even more I reckon. The yellow flags going both ways at the beginning is okay, the SC picking up any car isn't half bad either (you are either lucky or unlucky as a driver) as it might save a few laps getting the cars bunched up in the proper order. But what annoys me (and most marshals), is the green flag on every post as soon as the SC gets the last lap order somewhere around the track. Green everywhere but you are not allowed to overtake untill you reach the SF line.
Eh?
Asking for lots of problems I think, but who am I?
And I thought it only was silly in Belgium.
