(Help) How to change the speed on the AI track (F11 Editor)

Does anyone know how to change the speed of the AI tracks in the F11 editor to make it feel a bit more realistic?

 

You mean the speed of AI traffic? As far as I know there are only 2 ways, changing the width of the road (wider = faster speed) or setting up zones: https://documentation.beamng.com/world_editor/windows/sites_editor/

 

I placed the following in the mainLevel.lua for the map I am working on. The result is more speed in traffic but also more accidents . The function is called when traffic is loaded and starts to drive. This can also be achieved with the traffic app, but I wanted it to be adjusted automatically, every time traffic spawns on my map.
Unfortunately zones can only reduce traffic speed, imo, to be used for speedlimits.

(this is only the core code fragment)

Code:

local function onTrafficStarted()
    gameplay_traffic.setTrafficVars({baseAggression = 0.4})
end

Maybe this can help you a bit.
