Track layouts to receive AI line redos

Qualifying (and practice) has been a mess since the "AI actively look for space on track during practice and qualifying" feature was added. Particularly evident in multi class sessions. They do not "actively look for space on track", the behavior is as follows, encounter a car ahead (2 tenths or so), then go slow on straights, normal speed in corners, for the rest of the lap. No bule flag behavior. Repeats lap, after lap, after lap, until either they pit and repeat the behaviour or the session ends. This behaviour makes large grids and multi class practice and qualifying sessions pretty pointless. Unless the session is very long (>1hr) not all AI cars will make a representative laptime. Try a 10 minute session with 47 AI on a short or medium length track (<5km) and it is immediately obvious what a problem the "actively seeking clear track" behaviour becomes.

 

I did not race multiclass for a long time, so I have no idea how this works.
But in my single class races (with custom AI, some drivers are much quicker than others), there are some tracks where cars on fast lap meanwhile manage to overtake the ones on their outlap.
But on tracks with only short straights, they all still just stick to the line.
Weird thing in Imola 2001:
On the longest straight between last corner and "Tamburello", fast cars rarely manage to overtake.
The only spot I saw where an overtaking can sometimes happen, is the sector between "Tosa" and "Piratella".

In my AI-files, I set the value for "blue flag conceding" to 1.0, which is the highest possible value.
Apparently, this does not help much.

In general, the AI comes too close to car in front instead of going out of slipstream and goes for rear of car in front instead of using a gap in all classes. So, you often see ramming instead of overtaking..

 

The behaviour I describe is only observed in practice and qualifying. The ability of AI to overtake AI has always been terrible in any session. Blue flag overtaking has however improved recently.

I always use custom AI. Too many bad experiences with default Reiza AI. Would be interesting to see what values they use, sadly not possible! I would strongly advise trying blue flag conceding at 0, at least to compare behaviours. Certainly works better in my experience racing multi class but I favour racing in the middle speed class of 3. In multi class racing your own class slows far too much under blue flag conditions, even braking hard on straights!

 

If you set blue flag conceding to 0, they do not care at all about blue flags, which is a terrible experience in qualifying in single class races, because then, they block you on their outlap and destroy your lap by any means.
