Something that is REALLY bothering me, is that when you drive at night with AI traffic, they don't seem to turn their headlights on, and when I try turn their lights on, next time they respawn, the lights are off again!
I think you need to add a sentence that is about the suggestions like: It seems better when the script of lights control of AI driver, which detects time and turn on the lights when it is night.
For me, the AI turns the lights on when it gets dark in-game, through the environment tab. Are you running the official version of the game? Pirated versions can be outdated and thus, be more buggy/lack features. There's also the added risk of viruses/malware
At night time the vehicles will drive with there lights off until they respawn somewhere near you then there lights are on. what would be cool though is if the AI turned there lights on in tunnels (the tunnel in italy on the freeway is a good example)
