  AI is significantly slower than the player on long straights, as if they weren't going at full throttle, or have too much drag. In Historic Kyalami specifically, this is exagerrated because, due to the AI line, which misses the apex, the AI always gets a terrible exit out of the final corner. But even if I have an equally bad one, I'm still much faster than them on the straight using the default setup.

AI on Daytona (Wet Conditions)

I did a race at Daytona with mixed weather conditions. it also rains occasionally. The race lasted a total of 4 hours and after a stint I handed over my DPI to the AI (I was on P4). After an hour I returned and saw that the AI doesn't dare to overtake, instead it hangs in the rear in slower classes (GTE) and thus causes itself damage, so that it has to go to the pits every 2 laps for repairs (than P32 wirh mutch laps behind).
Unfortunately, changing drivers with AI makes absolutely no sense.

 

Delete - problem was on my end. Sorry for bothering you!

While the "pass in the grass" is an iconic stock car moment i don't think the whole field should attempt to recreate it every lap

 

McLaren GT4 AI 120 does this a lot.

 

Blue flag behaviour:
It got slightly better in races, but in training and qualifying, AI still blocks/fights faster cars on their in- and outlap like madmen.

 

Please make the AI safety car come safely onto the track and not just ignore the pitlane white lines, I almost had a heart attack xD

 

I believe all AI cars take this line out of the pits during a full course yellow.

 

Ive been playing around with AI and noticed that they never make mistakes, never crash or spin out. Also they occasionally slow down as you approach for the overtake and of course multiclass racing with a slow class and fast class seems to confuse the fast ai. They will just sit behind the slower class and wait till a long straight before overtaking.

Now is there a specific file I can play with to add some spice to the mix? I'd love to see some ai crash or at the very least overshoot a corner. I've been playing with ai ranging from 88 to 99.

Information for Customizing AI drivers in AMS2 V1.3

 

GT3 Gen 2 at Le Mans. Is there any use for videos like this ? Instead of having just a picture, here i have raw footage what the AI does or does not do.

 

Very nice report. The same general behaviour can be witnessed with open wheelers.

 

Draft strength and usage seems to be a constant trouble spot on both AI and multiplayer racing, specially on ovals. Hopefully Reiza can do a pass on aerodynamics and drafting now that the tyre physics are in a very good spot! Great video.

 

Yes, it also seems to me that oval racing is worse than it was before 1.5.5.4 patch, at Indy oval AI cars (F-USA-Gen1) slow down a bit (release gas pedal) more, it's a bit more erratic...

 

Anyone experienced some AI drivers going into the pits on lap 1 ?
This was the GT3 Gen 2 at Le Mans, AI set to 120 / Max, using a custom livery / AI pack:

While i have seen AI rejoining in safe ways and waiting for traffic to pass, it seems that it does not realize it should wait when drivers from a further distance are approaching, and the approaching AI does not know how to avoid a car on the road and instead sticks to their racing line, thus causing another crash.

 

He forgot to shout "Safe rejoin"

 

The AI since the last update is slower than previously, I beleive this is due to the wider margins they give the track limits and kerbs.
I like the fact that they seem to stay in the slipstream for a little longer before pulling out to overtake, the problem is that the tow effect is simply not as strong for the AI as it is for the player.
It seems to me that the loss of aero the AI suffers when compared to the player is too low. This affects both cornering in traffic and slipstreaming.

 

The draft / slipstream / tow effect basically does not exist from the AI, only time you see an AI overtake from what looks like the slipstream boost is actually the AI driver just driving faster on their own. I did many tests that showed the AI draft not working. See 0:23 as an example.
