[Question] destroyElement / optimization method ?

[Cronoss]

Well, I'm trying to optimize my server as much as I can, so I wonder if this -> destroyElement() would help. In this case, I'm deleting the player's car every time he quit the game, but I don't know if this is a good method or maybe this would cause problems in the future, I just need to know if this system it's fine for the purpose I want or it's wrong, I would appreciate an answer

The code (server-side):

function hideVehicle()
    local owner = getPlayerName(source)
    local askVeh = exports.mysql:_Query("SELECT plate FROM vehicles WHERE owner=? LIMIT 3", owner)
    if (#askVeh>0) then
        for _,row in ipairs(askVeh) do
            for k,v in pairs(row) do
                plateAsked = tostring(v)
                break
            end
                for k,v in ipairs(getElementsByType("Vehicle")) do
                    if (getVehiclePlateText(v)==plateAsked) then
                        setTimer( function ()
                        destroyElement(v)
                        end, 5000, 1)
                    end
                end
        end
    end
end
addEventHandler("onPlayerQuit", getRootElement(), hideVehicle)
