driver taking the racing line has priority.
This is still wrong (as I said before). Except in certain low-level racing series, there is no unfettered right to the racing line.
In general, the overtaking driver has the responsibility to make a safe pass, and both drivers (overtaking and overtaken) have the responsibility to maintain racing room. This means that in an overtaking maneuver through a turn, both drivers will have to leave the racing line in order to provide racing room to the other; the outside car must leave a car-width at the apex, and the inside car must leave a car-width at track-out.
The closest to a directly on-point quote that I can find for it is from the SCCA's GCR:
"Each competitor has a right to racing room, which is generally defined as sufficient space on the marked racing surface that under racing conditions, a driver can maintain control of his car in close quarters."
And, "The overtaking driver is responsible for the decision to pass another car and to accomplish it safely. The overtaken driver is responsible to be aware that he is being passed and not to impede or block the overtaking car."
It is the responsibility of the outside passing driver to make the pass or racing work without causing harm.
We clearly don't disagree on this point.
the Ferrari tried to maintain the ability to give room so a wreck didn't occur, thus it isn't irrelevant either way.
I thought and still think it looked like they pushed out too wide, and the most likely reason that IMSA rescinded the penalty is that they decided that the attempt to pass in that location was not safe, therefore the Ferrari had some latitude on track-out and got the benefit of the doubt that they did the best they could.
Especially when you take into account the post race interview Flying Lizard gave, claiming that they were pushed out and not given room. That picture indeed shows that during hard racing, the L5 still gave cushion.
The picture shows that there was still room about halfway through track-out, but it does not show that there was still room at the end of track-out.
Also if you agree Ferrari had no obligation to leave room why quote and argue me? Since we obviously agree on this, or your not being clear.
It ruffles my feathers when something is claimed to be definitive when it's clearly not. Even though I agree with the conclusion, I disagree (I think) with how you get there.
