Ai traffic bugs

#1 Post by jczarn2000 » 13 Jun 2026 13:58

1st issue: Ai traffic brake checks after performing lane change or overtake in front of player, forcing me to apply brakes. (This is a known issue since 1.59 update)

2nd issue: Ai traffic slows down / applies brakes when behind player and another ai vehicle when lane changing, this ideally needs adjustment to scs' game code for traffic (Known bug since the initial release)

3rd issue: Ai trucks keep unnecessarily lane changing into middle or outside lane when approaching any highway slip roads (exit and entering slips) causing unnecessary undertaking by other vehicles, this is causing the ai trucks to stay stuck in the middle or outside lane when other vehicles are undertaking in the inside and middle lanes. (Known bug from many game versions ago.)

4th issue: random ai traffic pop-in, both in front of player and clearly visible in wing mirrors, even adjusting the lod factor traffic in config.cfg doesn't fix or or reduce this. (Known bug from many game versions ago)

These bugs are happening everywhere on the map.

I don't have access to my pc at the moment due to other personal errands but this was 100% tested in fully vanilla. (no mods).
