I can only say that I think this is what you mean SpeedJ
Overtaking
O-1: To obtain right of road position in a corner, the overtaker's car must have substantial overlap of the car that is being overtaken, before they reach the corner's turn-in point. Should the overtaking car not have enough overlap, the leading car may resume its racing line without fear of contact.
O-2: The car on the outside has the right to outside room all the way through the corner – right up to the exit point. That car should not be squeezed against the outside towards the exit point.
O-3: The car on the inside has the right to inside room all the way through the corner - right up to the exit point. That car should not be squeezed against the inside towards the apex area. The ahead driver can still battle for the position of course but must do so while maintaining side room for the behind driver. The practice of going up the inside of an ahead car after that car has already turned in, and where there was no established substantial overlap before the turn-in point, is sometimes referred to as barge passing, (i.e. you barge your way past). Understand that barge passing is a high risk manoeuvre for both you and others. You have no rights what-so-ever as a barge passer.
O-4: Where an ahead driver has clearly made a sufficient error to warrant a passing move, a behind driver may attack their position, with due caution and care, regardless of whether there was any pre-existing overlap. E.g. - If the ahead driver brakes too late and drifts out wide of the apex and then has to reduce speed etc. This would be a valid passing opportunity regardless of whether there was pre-existing overlap. However, there is still substantial responsibility on the overtaking driver to take all necessary care to avoid contact. Small errors by the ahead driver may not be sufficient to justify an attacking passing move however. Just because the ahead driver gets a bit out of shape at times does not give you an automatic right to pass uncontested by them or a right to room. You still have to judge if their error provides sufficient opportunity for a safe pass to take place.
O-5: Ahead drivers have the right to choose any line down a straight. The ahead driver may make one move to block the opposing car, and one move to return to the racing line before the next corner - Unless the opposing car has overlap.
O-6: Ahead drivers have the right to take any line through a corner, unless an opposing car has overlap.
Lapping
L-1: It is a fundamental rule of motorsport and sim racing that when a driver receives a blue flag, this is to let the driver know that a faster car is about to overtake and put that driver a lap down.
L-2: The driver that is overtaking/lapping the slower car must treat the situation as though a normal competitor is being overtaken - and not assume the lapped driver should leap out of the way at all costs.
L-3: The driver that is being lapped should let the lead driver past and/or not resist to be overtaken. Only move out of the way for the lead driver when you believe it is safe to do so. For example, not on the apex of a corner.
Taking straight from the rulezzzzzzzzzzzzz
