  If a car is too close to overtake into the last corner, they will take a too shallow line, hit the inside wall and cause an accident of varying degree.
  
  Clip with an example:
  
  
  
  
  This goes in line with a previous report of cars clipping the sausage kerbs chasing others and destabilizing themselves. It seems to happen also with Aggression at Medium.

  AI will always dive into the pits when possible to repair engine and gearbox. On Grand Prix or shorter scheme of races, repairs of this kind should be limited to bodywork and maybe suspension (willing to give some leeway due to virtual world limitations), but not those inner mechanics (and this goes for both AI and player). This makes the attrition rates quite low, even though they do lose ground with these stops. But outside Azure Circuit, it's tough to recreate high attrition rate races with the AIs due to this.
  
  Example of this happening live:

  When facing a wall, an AI may take an eternity to get out because of not wanting to reverse enough to gain room to rejoin. They may lose a couple laps and cause a pileup anyway, or even quit the race, like at the example following below:
  
  

 

• Car / Track used: Formula V10 Gen 2 / Monza GP (observed at other places)
• AI Strength setting: 110
• Corner (if issue is corner specific): Irrelevant
• AI Aggression setting: High
• Session Distance: 53 Laps
• Weather when the issue was observed: Clear
• Player Tyre: Not racing
• AI Tyre (if known to be different from player): Irrelevant
• Type of session when the issue was observed (practice / quali / race) Race
  
  AI tends to do conservative lifts before braking zones if it has cars at gaps smaller than 3-4 seconds, but actually has no reason to do it. Example below:
  
  

 

• Car / Track used: Formula V10 Gen 2 / Monza GP (observed at other places)
• AI Strength setting: 110
• Corner (if issue is corner specific): Irrelevant
• AI Aggression setting: High

• AI Tyre (if known to be different from player): Irrelevant
• Type of session when the issue was observed (practice / quali / race) Race
  
  When following for an overtake, the AI pulls out of the slipstream too quickly when there is room to keep on drafting, sacrificing speed and negating its own chances. To make matters worse, when it still has a chance to overtake arriving at a braking zone, it prefers to get back in line mildly, lining its outside wheels with the car ahead's inner, sometimes bumping them and even coming on top of them if it misjudged the closing speed.

Just initiated by my reflexions on the comming new year I found this discussion about (Sonys) futuristic advanced AI called Sophy.
The video is just a banale hidden Sony ad (look how smart we are) but the comments are pretty thoughtfull me think.
And no I dont wanna waste my time talking about the pretty un-intelligent AI both in the sim close to us but also in all the other rather ordinary PC sims we have installed on our puters.
Happy new year.

Reiza, please finally have an eye on the blue flag behaviour of the AI.
They race you like crazy in their in- and outlap in qualifying, block you in corners and do anything to ruin lap of a fast car.
They do the same in races when they are about to being lapped.

 

Agreed. They should get well off the line and throttle on out/in laps as you approach during practice and qualy, as long as they’re not in the final sector of an out lap, then they can perhaps go full speed for their hot laps.

Currently, they move over on the straights, but don’t lift off the throttle at all, racing you into the corner.

 

And in the corner, they try to force their way through, ramming you off track. It is still the same as in day 1 of AMS 2.

some AI cut corner 2 extremly and then come nearly to stop, then continue racing (same cars also cut turn1, so they maybe lose their racing line)

 

It's a bit frustrating. I don't know how often my race was finished by AI this way.
AI wants to get on track without awareness and takes me out of race.

The AI is too slow, even at 120%. I am no alien and the AI is not very challenging. It's a shame, this class cars are so fun to drive. I know the entire galaxy is only talking about Le Mans/Endurance pack, but I hope these slow AIs will get some attention soon.

Can confirm this report, encountered the same behaviour in an LMDh race. The Carousel just highlights all the shortcomings of the AI. Also if they are already in "overtaking mode" and the player leaves a space on the inside through the Carousel they have infinite grip and just zoom past you on the inside.

AI in general is just all over the place at Road America

• brake too early into T5 (end of Moraine Sweep)
• takes the whole Carousel with a wide line instead of the staying mostly inside/middle through the corner - inside line is faster for me and also looking at IRL onboards it's the line drivers take - but the AI's wide line is magically much faster for them, while the player can't take the same line without losing significant time to them
• completely miss the apex through T11 (the kink)
• go way too wide through T13 (Bill Mitchell Bend) missing the apex, losing significant time here

  Ai exit first Speedway Bank on inside and stay to the left till near Bus Stop. But, then drift through the bus stop consistently. Drifting entering bus stop, then on exit.
  Porsche 911 Ai's in all classes are prone to wrecking or spinning due to drifting out of the bus stop and causes pile ups. Other cars can get unstable at times and then cause a pile up if there's traffic.
  
  BMW and Cadillac LMDH's also drift out of the turn and randomly may get unstable and slide out of a drift on exit of bus stop.

 

(copied from a different thread - TL;DR, AI at Bathurst seemed to not be affected by a 58c track temp at Bathurst)
---------------
I would like an opinion if this is an AI 'bug' or a calibration issue

Doing a GT3 Gen2 race at Bathurst, my normal AI level (100) and default set for the Porsche, started 32nd and really found it difficult to keep up in a short 6 lap race.

I thought it was probably just a calibration issue (that the AI is quicker at Bathurst), until I saw the results screen - the track temperature was 58 degrees celsius, and the leading cars still did 2:05/06 (I was low 08s lol, felt like my 'limit', at least )

So yeah, just a calibration thing or the AI is not slowing enough for a track temperature of 58c?

 

• Car / Track used: Nurburgring Nordschleife, modern version
• AI Strength setting: 100%-110%
• Corner (if issue is corner specific): Hatzenbach, red and white tyre bundle on the left.
• AI Aggression setting: Max
• Session Distance: 10 lap race
• Weather when the issue was observed: dry
• Player Tyre: dry
• AI Tyre (if known to be different from player):
• Type of session when the issue was observed: Race

When racing in a pack on lap 1, at least 1 car will hit the red and white outside tyre wall at Hatzenbach everytime. All classes of GT cars will do it. This happens with any AI difficulty, aggression on max, haven't tried the other levels. Dry conditions.

 

Doing various AI tests including ovals, the AI do seem to be able to make use of the draft but only when they "accidentally" enter it. They just follow a standard ideal line as if they were on a road coruse which also just results in them hitting walls on the right side or going below the apron when attempting a passing move where they should not do such a thing.
