04: Rules Governing Car Contact:
A: Contacts and collisions must be avoided at all costs.
D: Some contact through a corner or through a pass may not be avoidable and may be deemed "incidental" should it not appear to affect the likely outcome of the section in question.
Contradicting statements. The word "must" may need edited. Must is a command word meaning no other option is acceptable. Or simply remove rule A.
Just an observation.
I think I know what you are asking and this video might help. Go to 1:18 if you want to save time. Making contact in an attempt to make a pass must be avoided and may end up coming back on you if there is a complaint. Avoiding high risk, overly aggessive moves into corners will help
avoid the possibility of contact. The higher the risk taken the higher percentage chance of contact being made.
From "The Good Racecraft Guide"
An experienced racer will take whatever line he feels necessary into any given corner in order to defend & maintain his place, he is entitled to do so as he has track position over the pursuing driver, remember that the fastest line is not always the winning one. It is the other chaps job to force him into an error, whilst still driving cleanly of course, or wait for one to occur naturally & then take advantage of it, albeit in the proper fashion. An inexperienced racer will, in his endless optimism, tend to stuff it up the inside at every unavailable opportunity when trying to pass, imagining he is driving well but making far too much contact & causing many unnecessary incidents. Also, some lacking in good racecraft tend to drive right up to & into the driver in front, as they do not have the common sense to adjust their throttle & braking to account for following in the slipstream of another. You will notice that drivers who have good racecraft make very little contact when following & passing others on track.
...The undiscerning racer cannot tell the difference between a driver taking the correct racing line, & one going wide into these corners, he thinks the chap in front has made an error & stuffs it up the inside in a futile effort to overtake. When the driver in front accelerates towards the apex, the driver behind now finds he has placed his car in the wrong position, & there is contact.
In theory, this is what separates us from the typical "online lobby" experience where it is 3 wide into every corner or getting pushed around at every apex.
