I was rereading a pm and it brought up a reminder of something for the newer folks:
The answer lies in the rubber. Pay attention to the rubber that is laid down on track. It defines the true line, which is in the heart of that rubber. The way the rubber leads into the turn is important.
If you are struggling to find an efficient corner that feels “good”, you are likely not following that line. Frequently the track fools you to approach a corner un-optimally. The way the corner is set up makes you natural early or late to turn in because of how it presents visually.
Refer back to the rubber. Play with following it and you will find the entry line that allows your kart to rotate “just so” and naturally points you correctly for the subsequent apex.
Irl the rubber can be harder to see, alas. Green tracks are a thing.
