The F1 2023 Game AI Difficulty Comparison doesn't make much sense. It's what it is for him and highlights the track he is good at, not necessarily AI's fault.
I use the same level for hungry-spain-abu dhabi-Mexico, and I arrive between 6-9 (with my nooby car in myteam with all the pilots having 100 stats due to a stupid bonus) in all of them. (And I play a fixed level of 79 for all tracks.)
I do admit on the same track, I end up making more mistakes than others. For instance, Spain is very easy, while Mexico is kind of tricky, so I can understand why he feels Mexico is harder, but I don't think the time is wrong; it is just the fact that getting the correct entry-exit curve is not so forgiving and you end up losing a lot of tiny fraction of second each curve if you make a slight mistake. (And there are a lot of curves, so ultimately, my lap has a bigger delta between a good lap and a bad lap.)
