An idling truck on my street will fairly quickly raise my indoor co2 levels unless I shut the window. You also get particulate pollution. My guess is you’re right, and in your local area ventilation may not help. Though it depends on distance from the road. Dissipation happens fairly quickly with distance iirc. Haven’t been able to test at a freeway, mm co2 meter requires an electric outlet.
