Ai are slow on the exit of turn 7. They are also 1 second slower than me at this circuit compared to Brands Hatch Indy and I suspect the pace variance is at least partly due to their pace towards Coppice after their slow exit from McLeans. It is not just that Im faster than them through there, they are fairly obviously slow at getting on the power again between the apex of McLeans and the exit. It actually creates a collision risk because its so unusual and unexpected.

As reported for Brands Hatch Indy earlier, similar phenomenon at Donnington National- Ai are faster in the race than in qualification. Fastest Ai qualification time 1:18:966, fastest ai race time 1:18:423.

This means that all things considered, if you do a max performance lap in qualifying, on the same setup and with the same fuel as the race, you will be defensive all race as the race pace of the competition is a step up from their qualification pace. If you do a qualification setup that is faster then the problem will be compounded when you revert to your slower race setup.

AI is too slow through T1. They could do with being a touch faster in some other corners, particularly T5 (Knickerbrook), which they should be able to take at full throttle, and are a little slow at T3 & T7, but T1 is the one where they're most clearly much slower than they could be.

I find the AI in these two cars is always a little slow. I can usually get from last to first of 20 cars in a 5 or 6 lap race at most circuits I've tried. They just seem a fraction slow in many corners, which all adds up to easy overtaking most laps. For example, they need a little more aggression through fast chicanes (like the one at Santa Cruz), as I often find myself having to back off, or even slam the brakes, to avoid rear-ending them. Likewise going into corners. Chasing their bumpers through fast chicanes at top speed would feel be spectacular but they're often just a little below the speed they could be.

Maybe I just need to move up them a few % but I feel if I can easily beat them at 100%, they must be too slow. There are other cars where I can't get near them at 100%.

 

After having done some races after update to Version 1.2.1.0, there are two issues left to me:

1. AI coming from the back still tend to go for the rear side of players car before entering the corner, just as if they would not see the car in front. This can be horrible with oper wheelers, because the AI goes for your rear tyres and you spin.
2. They still cut corners and go over the grass without losing much grip/speed, when player is overtaking. On some tracks like Oulton Park, they cause huge carnage that way, because they hit the barriers in the chicane by cutting corners. On others, they just force there way back to the track, ramming the player on the racing line. The devs might reduce their grip level on grass dramatically (because they still drive over it like on rails now) or give them more respect for the car of human player.

Type of session when the issue was observed: Race

I just finished a race against AI drivers where I somehow went from P23 to P13 with only one "normal" overtake on the final lap. The reason seems to be lots of the AI going into the pits on the last lap. I'm attaching a picture of the standings at the start and end of my last lap, including ugly lines to indicate changed positions. I'm keeping the replay in case it's needed.

There were no changes in weather conditions that would've messed up strategies. Clear sky and dry track the whole time.

IF it's an underfueling issue, I wouldn't mind an AI driver occasionally doing it. Quite a human mistake. In this case it seems a bit excessive though.

I was up to 3 seconds faster per lap than the AI. I drove the Fusca HC2. AI seemed a bit slower here and there including the straights.

I match opponent pace well in many classes such as Copa Uno, GT3, Stock Car Brasil 2019 etc. Basically suggesting that I'm not a sudden mega alien against AI.

 

When overtaking on the inside, already in front of the AI before corners, they still love to brutally come over to your side as they were blind and ram. No matter which aggression level is in use.

 

Hope this is useful. I made this video to show the ability of the A.I. to slipstream each other, but it lead to me discovering (having not raced much with the modern formula cars much before), that there is a problem with the way the A.I. drive these specific cars (in this case Formula Reiza). I can't include the specific track, corner conditions as it seems to be a general problem across the board with these cars.

Basically the A.I. drive these cars like they would drive BTCC touring cars, with alot of contact and rubbing. This just does'nt happen IRL with these types of cars as F1 cars are pretty delicate and damaged v easily with the slightest contact. Maybe A.I. could be looked at for these specific cars.

Having said that, with the lower powered F3 cars the A.I. seem much better behaved.

 

P.S. this was with A.I. at 106% skill and about 60% aggression, in clear weather

 

Maybe aggression should be minimum for this type of racing, it does seems to show why the cars bunch up as momentum seems to drop to zero as soon as cars are side by side, watching Indy Car it can take 5-6 car lengths before the advantage has been lost.
Whatever it just feels and looks wriong for open wheel racing.

Racing the AI with this kind of cars is still a pain on many tracks because of their weird behaviour.

When going within the pack, the car in front is somehow brake testing you in corners, because it obviously brakes extremely late and then almost stands still on the apex, where it should have it's foot on the throttle again. So, if you follow this vehicle, you gotta brake a second time in order not to ram the AI in front.
At the same moment, the car in the back tries to overtake you by cutting corners and driving over the grass without any griploss, going for your rear tyres.
When player is coming out of the slipstream on straights and going for next corner, they just do not step back when already behind, but pretend on their line, wanting to go through corners side by side with you and often ram you out. They do not lose speed even if they are driving far away from the ideal racing line, because physics that affect player have no impact on the AI.
Devs might finally fix that, racing an AI with such "fantasy physics" can end up in a horrible experience.

Session Distance: 24 Laps
Corner (if issue is corner specific): 8 - Dunlop-Kehre
Weather when the issue was observed: Clear weather
Type of session when the issue was observed: Race

22 Lap I lead the race. Start overtaking Group C backmakers. Already breaking into turn 8 is a Opala (#1). 962 (#Me) Race down the straight behind Sauber backmarker (#2)
- #2 is not on the optimal line. Somewhere In the middle.
- #Me goes to the outside because I think he gives me room to overtake
- #2 slowly goes back to the outside and start to brake check me ~50-100 meters before the proper breaking point. #1 starts to turn into corner 8.
- #Me dives into the inside. Break hard missing apex a bit. Nearly colliding with #1, but Overtaking/Lapping #2
- Midcorner behind each other #1, #Me, #2
- Because #1 is slow #Me is waiting he goes to the outside so I can overtake him. I'm on tarmac next to the inner curb
- #2 starts to overtake me on the inner curb. But there is no room
- #2 executes a perfect police pit sends me into the inner guard rail. #2 only dips a break but is otherwise accelerating.

Bonus after recovering a with a bent racecar start to continue. A M1 appeared and pit me again more outward on the exit of the turn.

(Edit: continued and finished 5th. But I'm sure the complete residential block does know about my opinion about this move. Pretty sure the kids learned some new swearwords)

Type of session when the issue was observed: Race

Me in 962 other Group C pulls away on the start to break point at least two car length.

 

In the new version 1.2.1.2, I noticed that the AI gives you more space when going side by side (Formula Vee, F_V12) and do not exaggeratedly move over anymore pretending on a certain racing line.
But when player has to brake for slow AI in front, the guy from behind still goes for a gap which is not there and tries to overtake by going over the grass.

Session Distance: -
Corner (if issue is corner specific): Last corner (hairpin before finish line)

AI struggles with last corner and looses at least a second, probably more.
This makes AI very easy to beat in Long Beach. Both in quali and race....

Type of session when the issue was observed: All

AI do not turn on their rain lights on cars when the weather is set to light rain, or the wet track preset is selected (or both), even if there is a heavy spray. It is hard to judge where cars are in the spray. You cannot see the group of lancers ahead because of the spray and no rain lights.
