Superspeedway A.I. lines?

[justinehr18]

I have searched and watched Youtube videos, and I haven't really found anything about it. When the cars are single file, is there anyway to make them run on the low line right on the yellow line like they do in real life? When side by side 20 rows deep, a few cars will pull ahead in the corner, then when they come out of the corner, they go to the wall, instead of staying in line on the bottom. Any way to fix that? Thanks!

"Any way to fix that?"
That would seem to indicate there's something wrong with the current situation. The action you want is evidently not the action the track creator was looking for.
The ai can be "programmed" to run many ways, so yes, with many hours of work you can get the ai to run where YOU want.

Based on your description of the way the ai are running, I suspect they are following the race.lp. The ai will (more or less) always follow the race.lp unless they are looking to pass.
If they stay in line, it's 1) because they don't have the muscle to attempt a pass, 2) the minrace/maxrace lp's are not laid out to give them room to run side by side, or 3) the track.ini values (ai_drafting_distance, ai_dlat_pad) are inhibiting their ability to get in a position to pull off a pass.

ai...WHAT'S THE TROUBLE, WHAT'S POSSIBLE, HOW TO DO IT @NRTracks

Another thing I noticed, is when only in the Cup races, both with BR12 and with the new Gen 6 cars (thank you so much for completing it so fast by the way Bull Ring! Looks great!) when I'm running on any difficulty, generally I run in the 98% range, tried it all the way up to 100%, in turn 4, the cars will slow down to anywhere from 186 mph to 193 mph, which when doing 200 mph 3 wide, can get very annoying and dangerous. It's all of the cars, even when running by themselves they'll do it, I haven't messed with any of the settings, this is happening on the 2011 Daytona day track, and it's the only one. Any ideas? Thanks in advance!

Modify the race.lp and you can get em to run the bottom. But, dont expect passing. Theyll just run in a line. Its literally impossible to get the outside line to be an overtaking success by the ai. And i used to experience that slow down too but cant recall if i changed settings in the ini or if they just dont do it when i run. I have the ai at 102%. Lemme know if you need help w it. Maybe i can send my ini or summin.

Actually I saw that someone messed with the asphalt grip, so I turned mine up a little and it solved it!

Easy to do!!! I'm trying to modify this also, and obtained what you want.

1) replace race.lp by maxrace.lp (copy maxrace.lp and rename it race.lp - strangely, that's maxrace.lp which determine bottom line)
2) On track.ini :
ai_drag_modify = 1.06
ai_grip_modify = 1.06
play with both values to keep similar speed for AI.

And here you go: you got the boring race we had yesterday ! The main pack is single file racing, but sometimes you got 2-wide racing at the rear (3-wide only happened at start in middle and end of the pack). But be carefull : there will be no pass anymore in lead as the leader will never quit bottom line. You already know that the pole-sitter is the winner (except some problems in pits or with lappers).

Another test, and I obtained a quite nice racing at Daytona. on Revamped Reloaded 2011b base, I modified :

1. race.lp was replaced by minrace.lp (AI cars will keep/try to catch the upper line)
2. In track.ini :
[ ai_track ]
pace_merge_from_pit_line_dlong = 320.000
pace_merge_to_pit_line_dlong = 3650.0000
pace_speed_limit_mph = 70
ai_accel_modifier = 0.99
ai_decel_modifier = 0.90
ai_fuel_use = 1.10
ai_grip_modifier = 1.04
ai_drag_modifier = 1.04
ai_line_modifier = 1.02
ai_qual_modifier = 0.98
ai_wall_offset = 50
ai_tire_wear_left = 0.35
ai_tire_wear_right = 0.44
ai_arcade_tire_wear = 0.01
ai_arcade_fuel_use = 0.96
ai_arcade_grip_modifier = 1.0
ai_arcade_drag_modifier = 1.0
strategy_lap_time_wear_loss = 0.316
strategy_lap_time_fuel_use_gain = 0.118
strategy_base_pitting_cost = 59.756
ai_pacing_distance = 2.0
ai_bunching_distance = 1.7
ai_drafting_distance = 1.40
ai_panic_decel = 20.0
ai_dlongpad_scale = 10.0
ai_dlat_pad = 1.10
ai_squeeze_pcnt = 0.05
ai_inverse_slipcurve_k = 0.50

A driver can keep leading from 1 to several laps**, Mainly 3 wide-racing until the first restart, then mostly 2-wide racing with small ot medium packs (2 to 4 packs in 6-8 sec.). Some wrecks (from small one without DNF to big one - I'm still working on this by modifying ai_dlat_pad & ai_squeeze_pcnt values), and nice trajectories.
I'm racing at 107% with this.

** In one of my trials, Carl Edwards kept leading close to 15 laps before being trapped behind a lapper... Overtook him at 7th or 8th positions, and came back in top 5 in 3-4 laps.
