Well, I read the same article and it said a whole lot more than that including that it was impossible to predict every situation and make a rule for it, and that both the passing AND the overtaking car have a responsibility to protect each others safety. I distinctly remember a mention of each car owing the other enough room to survive the corner plus an inch at some point, or a statement very close to that. Did you skim the first couple sentences, get fired up, and sprint to the forum without finishing?
At our races there are always going to be drivers who have an incident and then debate their interpretation of who "deserves" to be given room in a corner and who "deserves" to be pinched off, forced wide, hit, spun, chrome horned, intimidated and/or wrecked. I consider myself unbelievably lucky to have avoided any major incidents so far in a fair amount of racing seasons. I attribute that to good judgement, control of my agression, and most of all racing around people who I respect, respect me, and understand that the only satisfying win is one taken cleanly from your competitors. I could give you a half dozen names right off the top of my head of drivers who were racing me hard but still looking out for me when I pulled a bonehead move and I have returned that favor to others just as many times.
The last thing I want is another rehash of the idiotic thread we had on here from a few years ago suggesting we should all paint a line on the side of our cars to indicate when a car was far enough alongside to "deserve" racing room. If you need that kind of thing, you just don't get it and are likely to be spending more time TALKING to the Steward than reading his column.
Be good to each other, protect yourself and your competitors and work for that clean pass.
