Is there any mods that would allow me to choose a certain range of years for the traffic ai? If not, would anyone be willing to do it? The only thing I'm good at is some simple blender skills, not much in programming. I'm not trying to push anyone, just asking.
I think that easiest is to spawn vehicles you wish to see, then get into car you wish to drive and from radial menu start traffic. If you need it for a mod, then that is bit beyond of what I can do.
