Lol, I think you badly underestimate the common sense of this field once the adrenaline starts flowing
Still, I've asked for something to be done about the double line too. I suggested changing the colour of one of the lines but apparently that was unnecessary or something.
Looks like there's just one line now, which elimintates the confusion, but also means that we now don't have much of a waiting line (whether thats a bad thing obviously depends on whether you think you need one).
As you go over the lines it can be difficult to see from a drivers perspective, i'd suggest bringing the SC line back more and going over the pit exit line to make it a bit more bold.
