Race management in the driving school car???

Hi guys, I had an experience of the third kind yesterday. I don’t need a traffic light and a driving school drives past me. Actually nothing unusual, you should think… Only the two gentlemen who sat in there didn’t look like driving students for me….so in a beautiful green race management uniform. I didn’t get a bad impression. Well, my question. Is there something you know that they do or have seen of you before? So I really to 9 0% sure that was my friend and helper!!! Greetings, BennyRay
