I agree with you. AI aggression can get out of hand at higher settings. It's still the best AI that I've raced against. I like the fact that they will try to come back on you after you pass them and they move over on the straights to defend. However, I am always a little extra careful at the beginning of the race if I'm not starting on pole.

I am trying to set up a multi class race on Le Mans with AI and the official rfactor2 GT3/GTE and LMP cars but it is just impossible. On the last chicane before the start/finish straight all the LMP cars spin out causing constant and massive accidents. I have tried letting the AI recalibrate but that does not change one bit. Either the built in AIW file is extremely messed up or something isn't playing nice with my PC. AI skill was set to 100 and aggression to 50.
Also, the GTE cars are slower than the GT3 cars. Maybe it's supposed to be like that though?
I might just give up on this game. ACC is probably getting an AI overhaul soon. Looks like the former King of AI, rFactor 2, is dying, tragically.
iRacing AI is pretty good. You can only use a few cars and not all tracks but they are pretty good, infact the best I think. The only down side is the driving experiance in i Racing is not the best. Especially braking (stability issues, lock up too easy, trailbrake oversteer) and lack of rear grip.
About 2 years ago the rFactor 2 AI with mods GT3 (Enduro racers & Apex Mods) was great. I was looking forward to the AI in paid content but its crap, I get rammed off track usually by AI re entering track and strtaight into me. Or I get bummed while braking for a corner, then they go slow through the mid corner through apex like an old grandma and off with rocket boosters attached and alien grip levels.
GTE cars are higher spec than GT3 in power, downforce & less assists like ABS & TC. That being said I struggle with Porsche RSR it seems slow compared to Ferrari and Aston.
I try using the LMP1 pack from URD but AI are driving Le Mans at lap record speed. Like super aliens.
I find once I learn the car and track 90 % is too easy but then 95% I get rammed while braking for corners or cut off. 25% aggression and 92% is what I use for endurance races but it seems hard to find the right setting.
I find the AI varies between tracks as well. You would think more development would be put into AI as the official stuff aint cheap. All sims are lacking in AI and it is annoying me as I enjoy doing proper races.
Personally I am not as fast as I used to be as I am using Fanatec V3 pedals with the pressure set to 90% and damper to max, giving me back pain from the required force so I reduced the pedal and voila I have a brake that is responsive and works well. Back to being fast. Anyway enough trivia.
You are completely right about the AI being pretty ok a year or a couple of years ago. I don't think they are worse in the paid DLC. They are just worse, period. Now they are blind as bats and behave like we are not even there. They never brake if someone has spun out. Full speed into the mayhem. Most of the time they continue on as if they hit nothing. Sometimes they touch a wall slightly and their wheels come off. They don't go around, they push through. They don't give way when they clearly has lost their position and they are happy to spin you out.
I have tried everything possible now. I let the AI calibrate (with the player.json settings) both with the ini-files and the wisdom files. They managed very good times when learning. But once I put them in qualification and race it all goes belly up. GTE end up in the middle of the field. intermixed with the supposedly slower GT3 cars, with one of the GT3 cars leading the pack. The LMP cars are thankfully qualifying on the top positions. But altough the LMP cars behave correctly in the practice, once the qualifying and race is on they keep spinning out between the two last chicanes on Le Mans. It looks stupid. It is stupid. AI mistakes are 0.0 in the player.json so it isn't caused by that. AI in the Porsche RSR also spin out at the exact same spot, every lap. So it's yellow flag and mayhem once the race starts. Every lap. If it had been a real race it would've been 30 cars in the pits or DNF after the first lap. Now they keep on truckin' despite their cars having damage. Unless they touch a wall and lose a wheel (game over for them even if they could limp back to the pits) they are unaffected by the damage. I guess in the same way the AI that takes over your car if you want to is unaffected by any damage you have sustained up until that point (as long as the engine still works).
The AI GT3 cars (except maybe the AMG that just bounces around on all curbs) behave nicely. But all cars are extremely slow in qualification and race. As in I can effortlessly take pole position even if I am 4-5 seconds slower than the pace AI had when in practice. And in practice they are about 5 seconds faster on Le Mans than what they manage in qualification. One GT3 (BMW I think) managed 4:01 something when learning. In qualification, 4:06. I suspect something is just really wrong. In comparison, the fastest GTE did 3:59 when I trained them, but in qualification the cannot muster 4:06 even.
Maybe it is the multi class wreaking havoc on the AI then, I thought to myself. Nope:
I ran a GT3 only quali/two session race, since they behaved the best. Same abysmal performance in the quali. I started 2nd. I kept 2nd for a good while. I overtook and became first. For a few laps I kept the AI at bay, but then I braked too late after one of the straights and lost it slightly. Number two rammed me off the track and continued on his merry way. My car was damaged, the AI:s apparently not. I DNF myself.
As I had set up for two races I started the next one last. I quickly gained positions. But there was one AI car that I could not keep at bay. As you mentioned about the rocket boosters - it sure seems like some of them have DRS or maybe NOS? Once I got past this one it shot away like a cannonball and overtook me again. It didn't get to draft me, it just blew past me like I was in a Nissan Sunny and it was in a Bugatti Chiron. But it was also painfully slow in the corners, so I could get easily get up beside it and overtake it, and I sure had the racing line but it didn't care. It turned into me and spun me out.
I sure do hope Studio 397 fix their AI soon. The FFB is the best around. I like the game. I can't afford iRacing. And other games might overtake the rFactor 2 AI completely. Check out Stefano Casillo (ex-Kunos) streams on Twitch. He's trying to improve the Assetto Corsa Competizione AI. And it's looking really good.
This is all why I mostly drive alone. I get fed up with AI ruining my races. What I find are biggest issues.
1. They can brake later so they ram you up the backside.
2. They are too slow mid corner, but have rocket boosters on exit.
3. When they leave track they return and hit you.
4. Cutting infront of you and trying to overtake in dangerous spots, such as they cut you off on corner, so you have to fumble about to not crash.
5. Inconsistant inbetween tracks, one track you win and another your last.
6. Too fast on straights. On portugal they swearve over to the right ride of the road and if your next to them boom, crash.
7. Some stages they crash too much
8. No blue flag, they dont let you past.
9. Hard to overtake as if you are in their line they hit you.
10. No proximity arrows or radar like ACC. You cant see them aswell.
11. As you said AI speed changes too much between sessions.
It is a shame as they used to be good. Oh well not as bad as Assetto Corsa AI.

The old ai were not perfect, but they were not this bad before. I mean if you make a change that is literally significantly decreasing the quality why not revert back to the better programming?
I mean you can go back and choose the 1109 build and have the good AI and quality races, but they seriously need to get the programming back from the 1109 build.
I forgot you can go back to these older builds, I will try that some day.
Overall AI is pretty quick on Silverstone except for Copse, the go wayyy to wide and have to brake.
I will do a AI learning, see if that helps.
the main thing is slow speed corners. AI in all games struggle to some extent with these, but between the 1109 and the 1110 build the AI went from being a little bit sloppy to being terrible. And while the actual steering imputs are for the most part fine, the issue is that the AI are now far less consistent with their breaking and gassing. I mean in the video I posted earlier showed the problem pretty well. They have a tendency right now to gas break gas break in rapid succession so that the car sounds like its using its engine to write a morse code message along with a constant strobing break light. which wasn't the case before and lap times have also suffered as a result of this
On the straits, in fast and medium speed turns the AI are fine. Some of the best in the industry actually.
The other issue is the aggression needs some tweaking. Now I am calling it aggression, but the aggression bar doesn't necessarly adjust theses issues. The AI are not very good at avoiding accidents with the player. So one example I can think of is if you break a late and hard in a circuit like le mans at the turns on the strait. Now I am not a super great sim racer so I have a tendency to not break super well and Find that I break a little and early since I am not super good at trail breaking. When this happens nearly every time I get rammed by the AI causing me to spin out and crash. As someone who likes to always run with damage on this in many cases ends my race. This is a bit frustrating especially when on the other hand the AI does a good job at defending and passing. But if they are not engaged in those behaviors, they seem to completely ignore the player causing accidents. Once caviat to this, however is I think there are deinately many actual people who would do the same thing who are following too close into the corners, but I would prefer the AI to loose some time following if it means I don't get run off the road every race even with the AI aggression at 0
As far as the AI crashing and causing saftey cars on various tracks with the inability to get through a corner, I do not blame rFactor for that (the exception being when its their map). Because that is actually map dependent. With the maps you need to have a good AI setup and thats completely dependent on the map maker. For a lot of mod tracks, the developers have no say in that. For their content, they do so that one is a map by map basis. The AI in slow turns is present on literally every map with low speed turns and it always breaks my immersion especially when it isn't present in early builds of the AI so that feature was actually broken.
