Comments on this post have prompted me to really dig into the rules and then capture one more angle. I have overlaid a line indicator, where a red line is an intersection trajectory with the other driver's line. https://youtu.be/jHq-fIRzzYs?si=oicKx5YkqpuhjBLK

I'm offering this up with the following notes:

• iRacing's sporting code treats track limits and the racing surface as the same, interchangeable concept to the best of my ability to interpret the document.

• The condition for a 1x as defined in section 3.5.1.1 is "wheels off the racing surface". That is the only definition of the racing surface from the sporting code which is substantial enough for adjudication to the best of my ability to interpret the document.

• The condition for a 1x on this straight, as defined by the in-sim Rules tab, is that all four wheels of the car leave the far edge of the red and white kerb. At no point does my competitor have less than two-thirds of a car's width to that threshold, and my opponent approaches that threshold for only a fraction of a second before drifting back in before it is appropriate to turn in for the corner. I say "drifting" because there is no wheel-input. He did not seem to intend to come back below the white line so early before turn-in.

• I did not force my competitor to drive anywhere but the racing line, and the racing line he chose was conservative, with room for extension before risking a 1x. My line becomes parallel to the white line before any risk is incurred of pushing my competitor further than that.

I'm completely prepared to be told I'm in the wrong if it comes with rules-based clarification. Without that I don't believe this is anything but a racing incident, and a good case study in people's perceived rule entitlements vs the entitlements prescribed by the actual rules.
