Unsolved Distinction between player and non-player at vehicle LUA

I'm trying to implement a performance mod with traffic and BeamMP in mind (mainly the logic here: [New Experimental] Increase FPS for decreased Damage Model by OfficialLambdax · Pull Request #487 · BeamMP/BeamMP · GitHub , with permission from original author @Anonymous-275 )

I'm trying to do it by injection into stage2.lua with a similar method as here: https://www.beamng.com/threads/0-29-1-performance-mod-selfcollisiondisabler.93250/#post-1614051

Problem: I don't want to apply it to the player vehicle. At stage2.lua playerInfo is not set yet and I can't get a be:getPlayerVehicle(0) call to GE lua working either.

So, how do I make a distinction between player and non-player vehicle at this stage of vehicle creation?

Code:

local stage2 = require("vehicle/jbeam/stage2")

do
    local pushToPhysics = ({debug.getupvalue(stage2.loadVehicleStage2, 1)})[2]
    local processNodes  = ({debug.getupvalue(pushToPhysics, 1)})[2]

    debug.setupvalue(pushToPhysics, 1, function(vehicle)

*do stuff if obj:getid() ~= playerVehicleId*

    debug.setupvalue(pushToPhysics, 1, processNodes)

        return processNodes(vehicle)
    end)
end

return stage2

 

For example, like this
