Missing ability to load AIhandling within FiveM

Since I made changes to the traffic nodes, AI is driving like crazy people and someone suggested that I create a special file which should make them slow down at corners.

However, trying to incorporate this into a script gives an error since is not being handled by FiveM at this moment.

What would it take to get FiveM to actually allow this to be loaded at server booting so that the AI can be adjusted accordingly ?

PS: I found an example file using OpenIV but that one is not working properly for the changes that I made.
