I managed to beat sophy on the 1v1 in tsukuba (by 0.021 sec) but not in the others. A few things I have noticed:
- I believe the less grip cars have, the more the AI has an "advantage". In the suzuka 1v1 with the porsche, I'm sure I could beat it or almost match it with a bit of trial (I only did 1 try for each event, But in the 1v1 in alsace with the GTR, I was something like 6sec of the pace a lap.)
- It lacks a bit of foreseeing. It take corner very fast, but often at the expense of exit speed. For example on mountain trial in the last corner, it take the actual corner much faster than me (several tenth) but i pull away in the following straight because i'm able the accelerate sooner.
-It's a bit too agressive in the corner, often raming you to the side to get past
But overall it's very fast and most importantly, it's feels more reactive to the player actions than classic AI. A slider to tailor the difficulty (50 to 100%) would be awsome to have close racing.
